Gregoria Mariska Tunjung Cahyaningsih (born 11 August 1999) is an Indonesian badminton player in women's singles. She started her career at the badminton club PB Mutiara Cardinal in Bandung, West Java, and was called to the national team in 2013. She was the girls' singles champion at the 2017 World Junior Championships. Tunjung also captained the Indonesia women's team at the 2022 Asia Team Championships, where they became champions.

Career
In 2014, Tunjung reached the final of the Malaysia International from qualifying round, beating among them the first seed Aprilia Yuswandari. Unfortunately, in the final round she was defeated by Chen Jiayuan in straight game. In 2015, at the age of 16, Tunjung became champion at the Singapore International, defeating home favorite Yeo Jia Min in the final. She later won the Indonesia International Challenge held in Surabaya.

In 2016, Tunjung won the silver medal in the girls' singles event at the Asian Junior Championships.

Tunjung opened the 2017 season by reaching the final of the BWF Grand Prix in the Syed Modi International. She finished as runner-up after her defeat to first seed and 2016 Olympic silver medalist P. V. Sindhu. She also finished runner-up to Kisona Selvaduray at the Indonesia International Series. In August, Tunjung obtained bronze medals at the individual and team events of the SEA Games. In October, Tunjung becomes the first Indonesian in 25 years to win the World Junior Championship girls' singles title.

Despite being a junior champion, Tunjung's senior career was quite tumultuous. In 2018, she won her only title that year at the Finnish Open, beating her compatriot Ruselli Hartawan in the final. She obtained a silver women's teams medal at the 2019 SEA Games, but did not won the individual event medals as she was stopped by Kisona Selvaduray in the quarter-finals.

Tunjung qualified for the Tokyo Olympics as the sole Indonesian representative in women's singles. Her Olympic debut ended in the round of 16 with a defeat against Ratchanok Intanon. She was part of the Indonesian team for the 2021 Sudirman Cup. Indonesia advanced to the knockout stage but lost at the quarterfinals against Malaysia. Later she competed at the postponed 2020 Uber Cup. Her results at the BWF World Tour tournaments were far from ideal, with second round exits at the European leg in Denmark, France, Germany, and home tournament Indonesia Masters, followed by a first round exit at the Indonesia Open.

Tunjung started 2022 on a higher note as the captain of the Indonesian women's team at the Asia Team Championships, winning all her matches from the group stage and contributing to their victory against South Korea in the final. However, her struggle in individual tournaments persisted, and her rank went down to 31 after her first round exit at the Indonesia Open. At the second half of 2022, Tunjung won bronze in the women's singles at the 2021 SEA Games, and obtained silver in the women's teams event. She then reached her first finals in the BWF World Tour event in the 2022 Australian Open. In the final, she lost to An Se-young in straight games. Thanks to her runner-up finish in Australia, Tunjung edged closer to qualify for the 2022 BWF World Tour Finals, and officially became the first ever Indonesian women singles player to qualify for the World Tour Finals after the withdrawal of P. V. Sindhu opened a spot for her promotion. She finished fourth in Group A standings with a victory against Chen Yufei and losses against An Se-young and Akane Yamaguchi.

2023
Tunjung kicked off the 2023 season with a poor performance, where she fell at the second round at the Malaysia Open against Hsu Wen-chi, despite an impressive victory against He Bingjiao at the first round. She also lost in the second round of the India Open, this time to Korean second seed An Se-young. She reached the quarterfinals of Indonesia Masters, where she lost against Han Yue. At the Asia Mixed Team Championships held in Dubai, Tunjung helped the national team made to the quarter-finals, but then Indonesia lost to South Korea 1–3.

Tunjung began showing visible progress with a quarter-finals finish at the All England Open in March, where she gave a tough fight to fourth seed and Olympic gold medalist Chen Yufei. This continued at the Swiss Open, where she finished in the semi-finals, losing to eventual champion Pornpawee Chochuwong.

Tunjung won her first ever BWF World Tour title at the Spain Masters by beating P. V. Sindhu in the final. This was also her first victory over Sindhu in eight matches. After this achievement, Tunjung's world rank rose to 10th, making her the first Indonesian women's singles player to enter the top 10 since Maria Kristin Yulianti in 2008.

In April, Tunjung advanced to the quarter-finals of the Asian Championships, but was eliminated by Chen Yufei in rubber games. Tunjung alongside the Indonesian team competed at the 2023 Sudirman Cup in Suzhou, China. She won two matches in the group stage, against Talia Ng of Canada and Yvonne Li of Germany. Indonesia progressed to the knockout stage but lost at the quarter-finals against China, where she again lost to Chen Yufei. In the following week, she again defeated Sindhu to reach her first ever Super 500 final in the Malaysia Masters, but lost to Akane Yamaguchi.

Tunjung suffered early exits in the Singapore, Indonesia, and the Korea Opens, before reaching the semi-finals in the Japan Open after defeating Yamaguchi. However, she had to concede defeat to He Bingjiao. Tunjung again faced Yamaguchi at the World Championships, but this time was defeated at the quarterfinals. She competed at the 2022 Asian Games but was unable to win any medal in both the team (lost to China) and individual events (lost to Aya Ohori).

In the European leg, Tunjung suffered two early exits at the Denmark Open and French Open, both against P.V. Sindhu. She bounced back at the Kumamoto Masters by defeating Chen Yufei in the finals, thus becoming the first ever Indonesian women's singles player to win a Super 500 or equivalent title since its inception in 2007. Afterwards, Tunjung exited the China Masters at the second round after losing to Nozomi Okuhara. Nevertheless, she secured her spot in the World Tour Finals as part of group A with An Se-young, Tai Tzu-ying, and Kim Ga-eun.

2024
She was selected as a member of the Indonesian women's team at the Uber Cup in May, and made history by reaching the final at the Uber Cup since 2008. In the final Indonesia lost to China 0–3.
