2019 Clube de Regatas do Flamengo season

The 2019 season was Clube de Regatas do Flamengo's 124th year of existence, their 108th football season, and their 49th in the Brazilian Série A, having never been relegated from the top division. In addition to the 2019 Brasileirão, Flamengo also competed in the CONMEBOL Copa Libertadores, the Copa do Brasil, and the Campeonato Carioca, the top tier of Rio de Janeiro's state football league.

The season was one of the most successful in Flamengo's history, as the team captured their second Copa Libertadores, seventh Campeonato Brasileiro Série A, and record 35th Campeonato Carioca. The team qualified for the 2019 FIFA Club World Cup by winning the Copa Libertadores, finishing as runners-up to UEFA Champions League winners Liverpool.

The season is marked by the tragic fire on 8 February at the Ninho do Urubu training center that claimed the lives of ten youth players who were sleeping in their rooms at the camp. The incident is considered the worst tragedy ever experienced by the club in its history.

Flamengo won their 35th Campeonato Carioca, defeating rivals Vasco da Gama across two legs in April.

On 1 June, Flamengo hired Portuguese manager Jorge Jesus after the resignation of Abel Braga. In June and July, Flamengo completed the signings of prominent free agent fullbacks Rafinha from Bayern Munich and Filipe Luís from Atlético Madrid, to play alongside the new signings of Gabriel Barbosa, Bruno Henrique and Giorgian de Arrascaeta. Flamengo were eliminated from the Copa do Brasil in the quarter-finals after a penalty shootout loss to Athletico Paranaense in the Maracanã on 17 July.

In August, Flamengo defeated Internacional to advance to the club's first Copa Libertadores semi-finals since 1984. On 23 October, the team defeated Grêmio 5–0 in the Maracanã to advance to their first Libertadores final since 1981. For the first time, the Copa Libertadores final would be played as a single match at a venue selected in advance. The location of the final was originally chosen to be the Estadio Nacional in Santiago, Chile. However, due to the ongoing Chilean protests, the match was moved to the Estadio Monumental in Lima, Peru. On 23 November in the final against defending champions River Plate, Flamengo trailed 0–1 in the final minutes before Gabriel scored twice to secure the 2–1 victory.

The day after the come-from-behind victory in the Libertadores, Flamengo became champions of the Campeonato Brasileiro with four matches in hand after a loss by Palmeiras to Grêmio in the 34th round. This was a Flamengo Brazilian title after a hiatus since 2009. This feat marked the first time a Brazilian club had won the Brazilian league and Copa Libertadores in the same season since Santos in 1962 and 1963. The title-winning campaign broke a number of records in the 20-team league format era (2006–present), including most victories (28), most points (90), most goals (86), best goal differential (+49), and most goals by a single player (25 from Gabriel Barbosa).

The team qualified to their first Club World Cup in Doha, Qatar in December, defeating Jorge Jesus's former club Al Hilal 3–1 in the semi-final before confronting Liverpool, the same opponent as the club's only world championship appearance and victory in the 1981 Intercontinental Cup. Both teams were closely matched in the final, ending regulation time in a scoreless draw. In the first half of extra time, Roberto Firmino of Liverpool scored the lone goal in Liverpool's 1–0 victory and Flamengo finished the competition as runners-up.

Ninho do Urubu fire
On the morning of 8 February, a fire erupted at the Ninho do Urubu youth training ground of Flamengo. The fire resulted in the deaths of ten academy players between the ages of 14 and 17 training with the club. Three others were injured. The cause of the fire was a malfunctioning air-conditioning unit that caught fire in the room of one of the victims close to 5:00. Intense storms caused flooding and tornadoes in Rio de Janeiro on the days before, likely requiring the training center to run on peak power. The location of the fire was the temporary living quarters in a newly expanded section of the campus. The state Labor Ministry launched a task force to determine if any preventative actions could have been taken, and to ensure that the families of the victims would be accommodated.

The victims of the fire were Athila Paixão (14 years old), Arthur Vinícius de Barros Silva Freitas (14), Bernardo Pisetta (14), Christian Esmério (15), Jorge Eduardo Santos (15), Pablo Henrique da Silva Matos (14), Vitor Isaías (15), Samuel Thomas Rosa (15), Gerdson Santos (14), and Ryckelmo de Souza Viana (17). Kauan Emanuel Nunes (14 years old), Francisco Diogo Alves (15) and Jhonathan Cruz Ventura (15) were hospitalized with injuries; Jhonathan's condition was the most severe.

Club president Rodolfo Landim described it as "the worst tragedy the club has ever experienced in its 123 years." The governor of the state of Rio de Janeiro declared a three-day period of mourning following the tragedy. The Taça Guanabara semifinal matches on the following days, including Flamengo's match against Fluminense, were postponed. Flamengo wore black ribbons on their shirts for all following matches in the season as a symbol of mourning in honor of the victims.

The Attorney General filed a lawsuit against Flamengo on 20 February requesting allocation of reparations to the victims and their families, and for the suspension of activities at the training center. The club entered mediation and negotiated directly with the families of victims, and were scrutinized for offering a lower compensation than the proposal from the Public Labor Ministry and the Public Defender's Office. On 27 February, the city of Rio de Janeiro officially enforced an interdiction of the Ninho do Urubu training center for the senior team (youth players had already been banned from the facilities after the fire). The interdiction is an enforcement of a penalty already applied to the training center in 2017 for operating without a valid license. The team moved their training activities to Gávea.

the center was released for use for the professional team in March and the youth levels in April, however players were not permitted to sleep at the center. On 24 May, the Childhood and Youth Court fully released the Ninho do Urubu training center for regular use.

In June, Rio police indicted former Flamengo president Eduardo Bandeira de Mello, along with seven engineers and technicians from Flamengo and the company that constructed the containers, on 10 counts of homicide and 14 counts of attempted homicide after concluding that the containers should not have been used as sleeping quarters. In July, the public prosecutor of Rio de Janeiro did not find sufficient cause to bring the eight defendants to trial, and granted 45 days for police to provide clarification on aspects of the investigation.

Season overview
On 19 December 2018 Rodolfo Landim was sworn in as Flamengo's new president after being elected on the 8th and officially took over official administrative roles on 1 January.

A deal was later reached to loan 20 year-old Jean Lucas to the São Paulo club instead.

On 3 April, in Flamengo's highest-attended home match of the season, the team lost 0–1 to Peñarol in the Copa Libertadores on a late goal by Lucas Viatri.

On 24 April in Quito, Ecuador against LDU, Bruno Henrique scored early before Flamengo conceded a goal in the final seconds of the first half. A draw would have guaranteed Flamengo's qualification to the round of 16 and LDU's elimination. Andrés Chicaiza of LDU scored an excellent goal in the second half to save his team from elimination. The result forced Flamengo to earn at least a draw against Peñarol in Montevideo on the final matchday to guarantee passage. Abel Braga was not present for the match, as CONMEBOL had suspended him for bringing his team out of the dressing room late after halftime against Peñarol.

On 27 April the 2019 Campeonato Brasileiro season began. Flamengo played host to Cruzeiro. Bruno Henrique scored twice and Gabriel scored on a rebound to put the match at 3–1.

In the final minutes of the match, substitute Vitinho failed to score on a one-on-one opportunity, but the draw was sufficient to qualify.

Still trailing by one goal, Diego and de Arrascaeta pressured Lucas Pratto to force a turnover. de Arrascaeta found Bruno Henrique who advanced into the attacking half before returning a through-ball to de Arrascaeta in the penalty area where he provided the assist to Gabriel's equalizing goal in the 89th minute. Minutes later, Diego lifted a deep forward pass into the area towards Gabriel. River Plate centre-back Javier Pinola failed to clear the ball and Gabriel scored with his first touch to complete the historic comeback. After trailing for much of the match, Flamengo won their second Copa Libertadores.

Gabriel Barbosa was named Man of the Match and finished as the top goalscorer of the Copa Libertadores with nine goals. Bruno Henrique was named best player of the tournament. The victory qualified Flamengo to their first FIFA Club World Cup in December in Qatar, as well as the 2020 Recopa Sudamericana against Copa Sudamericana champions Independiente del Valle. The result also likely qualified Flamengo to the expanded FIFA Club World Cup, which was to be played in China.

On 24 November, fewer than 24 hours after the finish in the Copa Libertadores, Flamengo clinched their sixth Campeonato Brasileiro championship as a result of Grêmio's 1–2 victory over Palmeiras. With four league matches still to play, Flamengo became the first Brazilian team since Pelé's 1962 and 1963 Santos teams to win the Copa Libertadores and Campeonato Brasileiro in the same season. With the championship, Flamengo qualified for the 2020 Supercopa do Brasil against Copa do Brasil champions Athletico Paranaense.

On 27 November with the league title already won, Flamengo took the field at the Maracanã against Ceará. Bruno Henrique scored his second hat-trick of the season en route to a 4–1 victory. The team received the Série A trophy on the field after the match. The victory set a new points record in the era of the league's current format (2006–present) with 84, surpassing Corinthians' 2015 total of 81.

December

On 1 December, Flamengo traveled to the Allianz Parque to face Palmeiras for the 36th round of the Brazilian league. Amidst public safety concerns and fear of clashes between supporters groups, CBF upheld the request from São Paulo police that visiting supporters not be permitted in the stadium, a decision which Flamengo opposed. Flamengo opened the scoring early with a goal from Arrascaeta and two from Gabriel, defeating Palmeiras 1–3. This was Flamengo's first victory at the Allianz Parque since its completion in 2014. The victory set another league record in the post-2006 era: 80 goals scored in the campaign surpassed Cruzeiro's mark of 77 from 2013. Additionally, Gabriel Barbosa broke the league goal-scoring record in the 20-team era with his 24th goal of the season, passing Jonas from 2010 Grêmio and Borges from 2011 Santos.

On 4 December Flamengo released their list of players for the Club World Cup.

On 5 December in their final home match of the season, Flamengo defeated already relegated Avaí by a score of 6–1 with a mostly reserve lineup. Gabriel scored his 25th goal of the season and 17 year-old Reinier scored a second-half brace. Flamengo finished league play undefeated at home.

On 8 December on the final matchday of the season, Flamengo suffered their worst loss of the year falling 4–0 to league runners-up Santos at the Vila Belmiro. With the defeat, Flamengo equaled the record for fewest losses in a 38-match season with four, a mark set by São Paulo in 2006 and Palmeiras in 2018.

On 9 December, several Flamengo players were honored at the 2019 Bola de Prata and Prêmio Craque do Brasileirão awards. Gabriel received the Bola de Ouro for best player of the season, and Bruno Henrique received the "Craque do Brasileirão" award for player of the year. Jorge Jesus was honored as the best manager of the year by both awarding bodies.

On 17 December Flamengo made their Club World Cup debut against AFC Champions League winners Al Hilal of Saudi Arabia in Doha, Qatar.

On 21 December, Flamengo and Liverpool entered the Khalifa International Stadium for the FIFA Club World Cup final and Flamengo's final match of the 2019 season. Forward Roberto Firmino of Liverpool nearly scored in the first minute of play. After resisting early chances, Flamengo matched Liverpool's play with chances from Bruno Henrique and maintained nearly 60% possession in the 1st half. In the 2nd half Firmino again came close, with a shot off the post. Éverton Ribeiro and de Arrascaeta came off for Diego and Vitinho. In 2nd half stoppage time, Liverpool was awarded a penalty after Rafinha fouled Sadio Mané on the edge of the penalty area, but the decision was reversed by VAR and the match went into extra time tied 0–0. Liverpool continued to pressure and finally scored in the 9th minute: Mané found Firmino in the box who scored the match's only goal. Flamengo was unable to respond, coming close with an opportunity from substitute Lincoln in the second period of extra time. Liverpool won 1–0, claiming their first Club World Cup with Firmino being named Man of the Match. Bruno Henrique received the Silver Ball of the tournament behind Mohamed Salah of Liverpool's Golden Ball.

On 31 December Gabriel was elected "Rey del Fútbol de América" ("South American Footballer of the Year") by Uruguayan paper El País. Teammates Bruno Henrique and de Arrascaeta finished second and third in voting.
