Janković won 15 WTA Tour singles titles and two doubles titles, with career highlights including the 2007 Wimbledon mixed-doubles title partnering Jamie Murray.

Family and early life
Janković was born in Belgrade, Socialist Federal Republic of Yugoslavia, as the third child of Veselin and Snežana, both economists. She has two brothers, Marko and Stefan. She is a student at the Megatrend University in Belgrade, studying economics. However, she has put her course of study on indefinite hold as she continues to pursue her tennis career. Janković learned her first tennis skills at the Tennis Club 'Red Star'.

As a $9 1/2$-year-old she was introduced to tennis by her elder brother and fitness coach Marko. She later trained at the Tennis Academy of Nick Bollettieri. As a junior, she won the 2001 Australian Open and reached junior no. 1 in the world. In 2001, she started to play on the WTA Tour; she reached the second round at her first tournament at the Indian Wells Open.

Tennis career
She was ranked world No. 1 for 17 consecutive weeks until she was overtaken by Serena Williams on 2 February 2009. She was the year-end world No. 1 in 2008, the first player in the history of the WTA Tour to do this without winning a Grand Slam title.

Janković has reached the singles final of the US Open and the singles semifinals of the Australian Open and the French Open. In 2007, she became the first female Serbian player to win a Grand Slam title when she won the Wimbledon mixed doubles title with British partner Jamie Murray.

2004–2006: Rising success
In October 2003, Janković entered the top 100 at No. 90 for the first time, after winning her first ITF title in Dubai. Three months later, Janković garnered her first top-10 win against Elena Dementieva in the first round of the 2004 Australian Open. In May, Janković won her first WTA title, a Tier V event, in Budapest, defeating Martina Suchá in the final. Following her win in Budapest, she reached No. 51 in the world. Elsewhere in her 2004 season, she defeated top-20 players Nadia Petrova (twice), Vera Zvonareva, Patty Schnyder, Elena Dementieva and Paola Suárez. Janković finished 2004 ranked no. 28 in the world.

In March, at Dubai, she advanced to the final following Serena Williams's retirement in the semifinal. Janković then lost in the final to Lindsay Davenport in three sets. She made her first Tier I semifinal in Berlin, losing to Nadia Petrova. In June, she reached her first grass-court final at Birmingham, but lost to Maria Sharapova. In October, Janković reached her third final of the year in Seoul, ranked No. 17 in the world, her highest ranking at that time, losing to 16-year-old Nicole Vaidišová in straight sets. Her ranking at the end of the season eclipsed her 2004 record at No. 22.

Janković lost in the second round of the Australian Open to world No. 188 Olga Savchuk. That was the first of ten straight losses, not winning a match from late January into early May. She later said this run caused her to consider quitting tennis. Janković ended her losing streak by beating world No. 17, Elena Likhovtseva in the first round of the Italian Open in Rome, before eventually losing to Venus Williams in three sets in the quarterfinals. At the French Open, Janković reached the third round for the first time, where she lost to world No. 1, Amélie Mauresmo.

At Wimbledon, Janković defeated sixth-seeded and defending champion Venus Williams in the third round in three sets. Competing in the fourth round of a Grand Slam event for the first time, she lost to ninth-seeded Anastasia Myskina. In August, Janković reached her fifth career final and first of the year at the LA Championships in Los Angeles, defeating Serena Williams (ranked world No. 108 at the time after a lengthy injury lay-off) in the semifinals, before losing to third-seeded Elena Dementieva in the final. The US Open saw Janković defeat world No. 10, Vaidišová in the third round, world No. 7 and former champion Svetlana Kuznetsova in the fourth round, and world No. 5, Dementieva in her first Grand Slam quarterfinal. In the semifinals, Janković lost to world No. 2, Justine Henin in three sets, after Janković had led 6–4, 4–2. Janković argued with the chair umpire, when the umpire refused to offer an opinion as to whether a service call had been correct, suggesting that Janković use one of her electronic challenges. Janković then lost ten consecutive games.

Janković continued her strong form in the aftermath of the US Open. Of the six tournaments she played during the remainder of the year, she reached the quarterfinals at five. This included a run to the semifinals at the China Open in Beijing, defeating world No. 7, Nadia Petrova in the quarterfinals, before losing to world No. 1, Mauresmo, in a third set tiebreak. Janković finished the year at a career-high ranking of world No. 12.

2007: World No. 3
To begin the year, Janković won the second title of her career at the ASB Classic in Auckland, defeating Vera Zvonareva in the final. The following week, at the Sydney International, Janković defeated world No. 7 and former No. 1, Martina Hingis and top-seeded Amélie Mauresmo on the way to the final, where she lost to Kim Clijsters after serving for the match. Janković's strong start to the year meant that some considered her a title threat at the Australian Open; however, she was eliminated in the fourth round by the eventual champion Serena Williams, who was ranked 81st in the world at the time. Because of her results at these tournaments, her ranking rose to world No. 10, the first time she had been included in the top 10.

Janković reached two semifinals in the Middle East in the spring, retiring against Mauresmo due to an ankle injury at the Dubai Championships, and losing in three sets to Justine Henin at the Qatar Ladies Open in Doha. Janković rebounded in the clay-court season, defeating Venus Williams on a third set tiebreak in the semifinals of the Family Circle Cup in Charleston, South Carolina. She went on to defeat Dinara Safina in the final to win the first Tier I title of her career. On European red clay, after losing to world No. 1 Henin in three sets both in the semifinals of the J&S Cup in Warsaw and the quarterfinals of the German Open (failing to hold a 4–0 lead in the third set in the latter), Janković won her second career Tier I title at the Italian Open, defeating second-seeded Svetlana Kuznetsova in the final. This results meant she entered the top 5 in the world rankings for the first time. Janković was the fourth seed at the French Open and one of the favorites for the title. After registering her third consecutive victory over Venus Williams in the third round, she went on to reach the semifinals of a Grand Slam for the second time in her career, but lost there to eventual champion Henin. This improved her ranking to a new career-high of world No. 3.

On grass, Janković captured the Birmingham Classic title, beating top-seeded Maria Sharapova in the final. Sharapova led 3–0 in the third set, before Janković rallied to win the match. The next week, Janković reached the final of the Ordina Open in the Netherlands and became the first player since Chris Evert in 1974 to win 50 matches in the first half of a year. Janković, suffering from a hamstring injury, lost the final to Anna Chakvetadze. At Wimbledon, Janković was the third seed, but lost in the fourth round to the surprise eventual finalist Marion Bartoli. In the mixed doubles competition at Wimbledon, Janković teamed with doubles specialist Jamie Murray to win the title in three sets by beating the fifth-seeded team, Jonas Björkman and Alicia Molik.

During the North American summer hardcourt season, Janković reached the semifinals of the East West Bank Classic in Carson, California but lost there to fellow Serb Ana Ivanovic, having held two match points in the final set. The following week, Janković reached the final of the Tier I Canadian Open in Toronto, where she lost to Henin on Henin's sixth match point. Janković had leads in the first and second sets, but was unable to maintain her lead. At the US Open, Janković lost to Venus Williams in the quarterfinals.

Janković's form tailed off following the US Open. At the Bali Tennis Classic, Janković was upset in the quarterfinals by former world No. 1, Lindsay Davenport, in Davenport's first singles tournament since giving birth. The following week at the China Open in Beijing, Janković defeated Davenport, but lost in the final to Hungarian teenager Ágnes Szávay, after Janković had a match point in the second set. Janković finished the year on a six-match losing streak, losing all three of her round-robin matches on her debut at the year-end WTA Tour Championships in Madrid. She finished the year ranked world No. 3. At the end of the year she had won 72 matches in a solar year, a true record of the WTA.

Janković had successful nose surgery immediately after Madrid to correct a breathing problem. The surgery prevented her from practicing for three weeks.

Olympic Committee of Serbia declared her the sportswoman of the year.

2008: World No. 1 and first Grand Slam final
Janković lost in the semifinals of the Australian Open to eventual champion Maria Sharapova in straight sets, having defeated defending champion Serena Williams en route. In March at the Tier I Indian Wells Open, Janković lost in the semifinals to Ana Ivanovic. The following fortnight, she reached her first final of the year at the Miami Open, losing to Serena Williams in three sets.

Janković started the clay-court season by losing in the quarterfinals of both the Family Circle Cup in Charleston and the German Open in Berlin. Janković then successfully defended her Tier I title in Rome, after defeating Venus Williams in three sets in the quarterfinals, receiving a walkover from the injured Sharapova in the semifinals, and defeating French teenager Alizé Cornet in the final. This was Janković's first singles title of the year. She went into the French Open among the favorites, following the sudden retirement of four-time champion Justine Henin.

However, she lost to compatriot and eventual champion Ivanovic after leading by a break in the third set. Janković was the only player to win a set against Ivanovic during the entire tournament. This marked Janković's fourth defeat in four career Grand Slam semifinals. She would have become the world No. 1 had she reached the final. However, she did reach a new career-high of world No. 2 in the week following the tournament.

At Wimbledon, Janković injured her knee during her third-round match against Caroline Wozniacki. Although she won that match, it visibly hindered her during her fourth-round loss to Tamarine Tanasugarn. Janković would have become the world No. 1 had she reached the semifinals of the tournament. However, she lost to Tamarine Tanasugarn in the fourth round. Janković squandered two further opportunities to immediately take the world No. 1 position with losses in the semifinals of the LA Championships to Dinara Safina and the quarterfinals of the Rogers Cup in Montreal, to Dominika Cibulková. Janković did eventually replace Ivanovic as the world No. 1 on 11 August 2008. She was the 18th woman to have been ranked world No. 1 by the Women's Tennis Association, but the first woman to have done so without ever having reached a Grand Slam final and only the third woman (the others being Amélie Mauresmo and Kim Clijsters) to have become world No. 1 without first winning a Grand Slam title.

Janković's reign as the world No. 1 lasted only one week, after she lost in the quarterfinals of the Beijing Olympics to eventual silver-medalist Safina. This meant Ivanovic reclaimed the world No. 1 position. Janković was the second seed at the US Open, where she defeated Olympic gold-medalist Elena Dementieva in the semifinals to reach her first Grand Slam final. There, she lost to fourth-seeded Serena Williams. Janković would have reclaimed the world No. 1 position if she had won the event.

Janković became the world no. 1 again during the fall in the midst of winning three consecutive tournaments. At the China Open, Janković defeated Svetlana Kuznetsova in two sets to win the title. The following week, Janković played in the Porsche Tennis Grand Prix in Stuttgart, where she defeated Venus Williams in the semifinals and Nadia Petrova in the final. In the Kremlin Cup in Moscow, Janković defeated defending champion Dementieva in the semifinals before triumphing against Vera Zvonareva in the final for her third title in three weeks, the first time for a player on the WTA Tour to do so since 2005.

As the top seed at the year-end 2008 WTA Tour Championships held in Doha, Janković won two of her three round-robin matches, including only the second win of her career over Ivanovic. However, she lost in the semifinals, to eventual champion Venus Williams and ended the year as world No. 1. In all, Janković lost to eventual champions at six tournaments (including three Grand Slam tournaments) during the season. Janković was later named the ITF World Champion for her performance in 2008. She won four titles during the season, the most of anyone on the tour along with Serena Williams and Safina. The Olympic Committee of Serbia declared her the best sportswoman for the second year in a row.

Janković was seeded first at the Australian Open in Melbourne. She lost to 16th-seeded Marion Bartoli in the fourth round.

She faced top seed Petra Kvitová for a place in the quarterfinals but retired midway due to right hip injury.

Despite coming to North America with 2–4 season record, Janković made the final at the Indian Wells Open, beating reigning Australian Open semifinalist Madison Keys, Belinda Bencic and Sabine Lisicki en route. In the final where she faced Simona Halep, she managed to take the first set and serve for the match, but came up short. As a result, Janković returned to the top 20. In Miami, Janković fell in her opening match for the second straight year when she was defeated by Victoria Azarenka.

In April at the Family Circle Cup, Janković made the third round, conceding a walkover to Danka Kovinić due to an injury. The following month at the Italian Open, Janković overcame Camila Giorgi and Magdaléna Rybáriková to set up a third round clash with Kvitová for a place in the last eight but was defeated by the fourth seeded Czech in straight sets. Janković then played in Strasbourg where she reached the quarterfinals but was forced to retire against Sloane Stephens. Janković then suffered her second consecutive opening round at a Grand Slam when she fell to qualifier Sesil Karatantcheva in straight sets at the French Open.

Janković's grass court season began in 's-Hertogenbosch where she was the second seed. She routinely advanced to the semifinals where she faced Bencic but lost in straight sets. At the Birmingham Classic, Janković defeated Tereza Smitková and Casey Dellacqua to advance to the third round. She lost to eventual champion Angelique Kerber. Janković won first two matches in three-setters at the Wimbledon Championships and then made the biggest upset during the tournament by taking out the defending champion and world No. 2 Kvitová in the third round, having lost their two previous matches this year. She fought back from a set and a break down to prevail. Her win granted her a place in the fourth round, where she lost to Agnieszka Radwańska. It was the first time since 2010 that Janković made the second week and won consecutive matches at Wimbledon; her performance also made 2015 the first year since 2007 that Janković won more than five grass court matches.

After losing in the first round of the Istanbul Open to Urszula Radwańska, Janković won the WTA 125 title in Nanchang by defeating Chang Kai-chen. She did not drop a set throughout the tournament. This tournament revitalized her career and opened her path to a successful Chinese hard court season, right after the second round of the Rogers Cup and an excellent semifinal in Cincinnati after beating Madison Keys and eighth-seeded Karolína Plíšková en route. Janković then suffered a shocking loss to wildcard Océane Dodin in the first round of the US Open.

Janković completed a great Asian swing and confirmed her excellent results in China by winning her 14th career title in Guangzhou, her first since 2013. She saved match point in the semifinals against Yanina Wickmayer, before losing just two games in the final against Denisa Allertová. At the Wuhan Open, Janković defeated Heather Watson in the first round in three sets. She faced sixth seed Angelique Kerber in the second round but lost in three sets. Janković won her third title of the season (and milestone 15th career title) at Hong Kong by battling past Venus Williams in the semifinals in a tight two sets win. Janković then hung tough against world No. 9 and top-seeded Angelique Kerber (Janković's third top-ten win of the year), coming back from a set down to capture the title with a three-set victory.

2016: Injuries and loss of form
Janković started her 2016 season in Brisbane, but lost in the first round against recent US Open finalist and eighth seed Roberta Vinci in three sets despite being up a set. She then traveled to Sydney and won her first-round match against CoCo Vandeweghe in straight sets. However, she fell to Sara Errani in two tie-break sets in the second round despite being up 5–1 in the second set. Seeded 19th at the Australian Open, Janković won her first-round match against Polona Hercog. She suffered a second-round upset at the hands of Laura Siegemund.

During the Fed Cup tie versus Spain, Janković lost both of her matches to Carla Suárez Navarro and Garbiñe Muguruza. Serbia ended up losing 0–4. At the Dubai Tennis Championships, Janković upset fifth seed Belinda Bencic in the first round to get her first top-10 win of the season. However, she lost in the second round to Andrea Petkovic. Seeded 14th at the Qatar Ladies Open, Janković was tested by qualifier Jana Čepelová in the first round but managed to win in three sets. She exited the tournament after losing to Monica Niculescu in the second round. Janković then went to Indian Wells having to defend finalist points from the previous year. Seeded 19th, she received a bye into the second round and beat Carina Witthöft in straight sets. Janković then dominated CoCo Vandeweghe in her third-round match; she only conceded one game. She then lost to third seed Agnieszka Radwańska in the fourth round. Seeded 18th at the Miami Open, Janković withdrew from her second-round match against qualifier Magda Linette due to a right shoulder injury.

Her clay-court season didn't open so well as she was forced to withdraw from the Charleston Open because of the right shoulder injury she sustained in Miami. Janković returned to action at the Madrid Open. She lost in the first round to Sorana Cîrstea. At the Italian Open, Janković was defeated in the first round by Eugenie Bouchard. Seeded 23rd at the French Open, Janković lost in the first round to Tatjana Maria. Janković opened her grass-court season at the Rosmalen Open.

Seeded 22nd at the Wimbledon Championships, Janković lost in a second round thriller to qualifier Marina Erakovic.

Seeded second at the first edition of the Ladies Championship Gstaad, Janković suffered a first-round upset at the hands of world no. 797 Rebeka Masarova. As the top seed at the Brasil Tennis Cup, Janković fell in the second round to Ana Bogdan.

Janković ended the year ranked 54.

2017: Recovery, continued struggles with form and worst ranking since 2003
Janković started her season at the Shenzhen Open where she lost in the first round to second seed Simona Halep. Next, she progressed to Hobart where she suffered a tough first-round defeat to third seed and eventual finalist Monica Niculescu. Conveniently, Janković gave, arguably, her best performance of the year at the Australian Open. She beat 26th seed Laura Siegemund and Julia Görges in her first two rounds. In the third round, she faced eighth seed and longtime rival Svetlana Kuznetsova. Kuznetsova ended up outlasting Janković in the third set 9–7 in what is currently the third-longest main draw match in Australian Open history.

As the eighth seed at the Taiwan Open, Janković was stunned by Kurumi Nara in the first round, despite having taken the first set. Janković found herself needing to qualify for the main draw at the Qatar Ladies Open, and she did so successfully. However, she was defeated in the first round by Anastasia Pavlyuchenkova. The following week, Janković played at the Dubai Championships where she lost in the first round to German wildcard Mona Barthel. In March, Janković competed at Indian Wells where she defeated American wildcard Irina Falconi in the first round. In the second, she was up against 12th seed and rival Venus Williams. Janković raced to a one-set lead and appeared on course to the third round when Williams began finding her range. Janković squandered match points before losing a second set tiebreak and, eventually, the match. As a result, Janković's singles ranking dropped to 54. This loss would tie up the rivalry between Janković and the seven-time Grand Slam champion at seven wins apiece. Janković started the second leg of the Sunshine Swing in Miami with a first-round loss in a third set tiebreak to Yaroslava Shvedova.

Janković began her clay-court season at the Charleston Open where she defeated Ekaterina Alexandrova in the first round. She was defeated in the second by sixth seed Sam Stosur. At the Prague Open, Janković lost in the first round to eventual finalist Kristýna Plíšková. At the Madrid Open, Janković was defeated in the first round by fourth seed and last year finalist Dominika Cibulková. Playing her final tournament before the French Open at the Italian Open, Janković lost in the second round to Julia Görges. Ranked 63 at the French Open, Janković was defeated in the first round by qualifier Richèl Hogenkamp.

Janković had a very poor grass-court season. She suffered a first-round loss at the Rosmalen Open to qualifier Petra Krejsová. At the Mallorca Open, Janković was defeated in the first round by third seed and defending champion Caroline Garcia. Ranked 67 at the Wimbledon Championships, Janković lost in round one to ninth seed Agnieszka Radwańska.

Seeded sixth at the Jiangxi International Open, Janković was defeated in the second round by Chinese qualifier Lu Jingjing.

In Washington, Janković retired in the third set of her first-round encounter with fifth seed Océane Dodin due to back pain. At the US Open, Janković lost in the first round to thirteenth seed Petra Kvitová.

Janković underwent back surgery in October; she has not played another tournament since then. She ended the year ranked 153, her worst ranking since January 2003.

2018–2019: Uncertainty looms
Due to her back surgery in October 2017, Janković missed the entire 2018 and 2019 seasons. She also underwent eye surgery in May 2018, further delaying any comeback plans. For the first time since 2001, she was unranked in the WTA singles rankings.

2022: Retirement
Janković did not participate in any WTA tournaments prior to the suspension of the tour due to the COVID-19 pandemic. Janković announced on Instagram that she would participate in an exhibition tournament in Belgrade, partnering with Novak Djokovic in a mixed doubles match. This was her first tennis match since September 2017. After the match, Janković admitted that she still was uncertain about a possible comeback on the professional tour. Janković eventually announced her retirement in July 2022, saying she has accepted that her body no longer allows her to play professional tennis and that she would make her health and her child, a priority.

Janković vs. Ivanovic
A prominent rivalry in women's tennis was the one between Janković and fellow Fed Cup teammate and Serbian compatriot Ana Ivanovic. They have met 12 times, with Ivanovic leading 9–3 overall. Seven of their eleven meetings have come at important stages of tournaments, while two have come at Grand Slam tournaments; Janković trails in both categories 1–6 and 0–2 respectively. Both players were touted as future top players following their breakthrough in 2007 and 2008, however, both have since underperformed on the WTA Tour and dropped out of the Top 10 in contrasting circumstances. Matches between Janković and Ivanovic are often given the nickname "The Battle of Serbia". Since the end of 2008, both have struggled at the Grand Slams, with Janković only being able to reach the semi-finals of the 2010 French Open and the quarter-finals of the 2013 French Open and Ivanovic the quarter-finals of the 2012 US Open and 2014 Australian Open, and the semi-finals of the 2015 French Open.

Their most important meeting to date was in the semifinals of the 2008 French Open; the match was one of historic proportions as it would decide which of the two would become the first Serbian player, male or female, to gain the world No. 1 ranking. In a match that lasted three sets and saw one player try to gain authority over the other, Ivanovic prevailed; the result saw Ivanovic claim the world No. 1 ranking for the first time, however Janković would herself claim the ranking later that year.

The pair were involved in a long-running feud in early 2010, arising from Ivanovic's decision not to play in Serbia's Fed Cup World Group play-off against Slovakia due to her poor form at the time. They met in a controversial encounter at the Madrid Premier Mandatory tournament in May that year, in which Janković appeared to criticise and imitate Ivanovic's fist-pumping habit following a three-set victory. It was only Janković's third (and most recent to date) victory against Ivanovic, after previously winning in 2006 and 2008.

At Indian Wells in 2011, Janković was the defending champion, but Ivanovic defeated her in the fourth round, ending her title defence. That would be their last meeting in a WTA Tour match until the 2013 Australian Open, where Ivanovic prevailed in the third round. Their most recent meeting was in the semi-finals of the Porsche Tennis Grand Prix in 2014 with Janković losing again in straight sets.

List of all matches

Janković vs. Zvonareva
Jelena Janković and Vera Zvonareva have met 14 times with Zvonareva leading their head-to-head 8–6. Their first meeting was in 2005 with Zvonareva winning a second round match in Rome.

They met six times in 2008 with Janković winning four of the six meetings, including three consecutive times in three consecutive tournaments during the fall. The third match in this streak was the final of the Kremlin Cup, which was the third consecutive title won by Janković in a stretch which also included titles in Beijing and Stuttgart. Janković had defeated Zvonareva on her way to the two titles which preceded the Kremlin Cup. However, Zvonareva would defeat Janković at the WTA Tour Championships later that year; this would be the start of an ongoing five-match winning streak against Janković.

Their only meeting at a Grand Slam tournament was at Wimbledon in 2010, in the tournament's fourth round. Zvonareva won, reaching her first quarter-finals of the grass court Major (and eventually went on to reach the final), after Janković retired whilst trailing in the second set.

Their most recent meeting was at the Qatar Ladies Open in 2011 with Zvonareva winning in three sets. It was her fifth straight victory over Janković, dating back to 2008.

List of all matches

Janković vs. Venus Williams
Jelena Janković and Venus Williams have met fourteen times and each player has won seven times. Janković leads 4–2 on clay courts and 1–0 on grass, whilst Venus leads 4–1 on hard. Their rivalry is one of the most competitive and even in women's tennis. Only three of their matches have been decided in straight sets: their first meeting in the quarter-finals of the 2005 East of the West Bank Classic, which Venus won; the second was in the quarter-finals of the 2010 Internazionali BNL d'Italia which Janković won with 6–0, 6–1; this was the worst ever defeat in Venus Williams' entire career, and their third and most recent meeting in the second round of the 2012 Family Circle Cup, which Venus won in straight sets.

They have met three times in Grand Slam tournaments. Janković caused an upset at Wimbledon in 2006 where she defeated the defending champion in the third round, winning in three sets. They met twice at the Majors in 2007, Janković winning at the French Open, and Williams winning at the US Open in 2007. Both matches required a third set.

They have also met twice at the WTA Tour Championships, both times in the semifinals with Williams winning in three sets on both occasions. Their most recent meeting transpired in the 2017 BNP Paribas Open in Indian Wells, California. Janković appeared on her way to victory in this second round meeting at 6–1, 4–1 up before Williams came racing back to win a 2nd set tiebreak and force a decider, which she proceeded to win 6–1 en route to the quarterfinals.

List of all matches

Janković vs. Serena Williams
Janković and Serena Williams have met 14 times, with Serena leading 10–4 overall. Their first seven matches and the last match were on hardcourts, which Serena leads 7–3. The eighth and tenth match were on clay and the ninth was on grass.

In 2004, they played their first match in San Diego; Serena won in three sets. The second match was at the 2005 Dubai Tennis Championships semifinal, with Janković causing an upset (Serena was world No. 4). When Janković was leading 6–0, 4–3, Serena retired. She is one of nine players who won a 6–0 set against Serena. The others are Venus Williams, Martina Hingis, Mary Joe Fernández, Justine Henin, Patty Schnyder, Anabel Medina Garrigues, Simona Halep, and Johanna Konta.

Janković won at the LA Women's Tennis Championships in 2006 in straight sets, and Serena won at the Australian Open in 2007. At the Australian Open in 2008 quarterfinal, Janković won in two sets.

At the 2008 Sony Ericsson Open, Miami, they met in a final for the first time. Serena won in three sets. They played again in the final, and again in USA – at the US Open in 2008. Serena won in two sets. In the second set Janković had 5–3 and three consecutive set points on Serena serve. Later, when she was serving for the set at 5–4, she missed one more set point. However, Serena saved all set points and won four games in a row for US Open title.

Two years later, in the semifinal of the 2010 Internazionali BNL d'Italia Janković won in three sets, saving match point in doing so and coming back from 5–2 down in the final set tie-break. In the quarter-final she had defeated Venus Williams, becoming the only woman to defeat both of the Williams sisters in a 24-hour period. Their opening round match at the Tennis at the 2012 Summer Olympics was their first and only match on grass. Janković wasn't seeded and Serena won in two sets before going on to win the gold medal.

At the final of the 2013 Family Circle Cup, Charleston, Serena won in three sets. Again in 2013, at China Open, they met in the final and Serena won in two sets. At WTA Championships Serena won their semifinal match after losing second set convincingly, 6–2.

Their most recent meeting occurred in the quarterfinal of the 2014 Western & Southern Open, where Serena won in straight sets. Serena improved to 6–0 record since it was 4–4.

Janković vs. Justine Henin
Jelena Janković and Justine Henin met ten times over a span of six years with Henin prevailing each time. They never met on carpet or grass. Five of their matches were on clay and five on hard courts. Six of their matches went three sets. The majority (7) of their matches occurred during the 2007 season. They met twice in Grand Slams (2006 U.S. Open semifinals, 2007 French Open semifinals) as well as the round-robin stage of the 2007 tour championships. Despite their lopsided head-to-head results, their matches were always highly competitive.

List of all matches

Playing style
Jelena Janković is a defensive baseliner, and is often regarded as a counterpuncher. Janković is known for being able to slide effectively on all surfaces. Janković has very consistent groundstrokes and prefers to go down the line more often than crosscourt. Her biggest weapons are her two-handed backhand, especially down the line, and the drop shot. She also has a decent forehand. Her net game has improved as a result of additional doubles play, meaning that she is now able to hit effective drive, drop and swinging volleys. Her main weakness is her serve. She likes to spin it in on the first and second serve which can lead to her getting broken many times in matches. Her weakest surface is considered grass and her best surface is fast hard courts, where she can use her defensive skills and speed to win matches. However, given the fact that six of her fifteen titles have come on clay, this could also be considered her best surface. One of the most high-profile achievements of her career occurred on grass in the third round of the 2015 Wimbledon Championships, when she defeated Petra Kvitová, the defending champion, a two-time Wimbledon title holder, then-no. 2 in the world (when Janković had dropped to world no. 30), and the only player who had defeated Serena Williams that year. Janković's ups and downs are often caused by her fragile mindset (see US Open 2006 vs Henin), and they have resulted in her being nicknamed 'Queen Chaos.'

Personal life
Janković was the subject of the 2008 autobiographical documentary, Jelenin svet (Jelena's World), featuring Justine Henin, Svetlana Kuznetsova, Ana Ivanovic, Elena Dementieva, Anna Chakvetadze and other notable players.

On 5 December 2007, Janković became a UNICEF National Ambassador for Serbia, for Children's Fund. "I am happy to have become a UNICEF ambassador for Serbia. This is a great honour for me and I will try to justify the role that has been given to me", she said. Janković is the second Serbian tennis star to have volunteered to help promote the rights of children and collect funds for UNICEF after Ana Ivanovic became an ambassador in September.

Janković is a cousin of Serbian singer Dijana Janković, internationally better known as Didi J. On 6 April 2021, Janković gave birth to a baby girl in Belgrade, Serbia.

Endorsements
Janković is currently sponsored by Italian sportswear company Fila. Previously, Janković had endorsed Anta and Reebok sportswear, and had her own line with them for her tournament wear. Janković also has an endorsement with Prince Sports: in her early career until 2007, she played with the original Prince O3 Red; from 2008 to 2010 she used the Prince O3 SpeedPort Pro White; from 2011 to 2013 Janković played with different types of racquets and in 2012 and 2013 she chose blacked out ones; since January 2014 Janković has been playing with the Prince O3 Red LS.
