Marta Kostyuk is a prominent Ukrainian professional tennis player with remarkable achievements on both the WTA Tour and the junior circuit. She reached career-high singles and doubles rankings of world No. 16 on June 17, 2024, and No. 27 on May 8, 2023, respectively. Her accolades include one WTA singles title at the 2023 ATX Open and two doubles titles from the 2022 Slovenia Open and the 2023 Birmingham Classic. Her standout Grand Slam performance came at the 2024 Australian Open, where she advanced to the quarterfinals.
Born on June 28, 2002, in Kyiv, Ukraine, Marta Kostyuk comes from a tennis-oriented family that shaped her early passion for the sport. Her talent emerged quickly, and in December 2015, she won the “14-and-under” category at the prestigious Junior Orange Bowl in Florida. Continuing her streak of junior success, she claimed victory at both singles and doubles events at the 2016 Petits As in Tarbes, France.
In January 2017, Marta Kostyuk secured her first major junior title by winning the girls’ singles at the Australian Open. Later that year, she achieved another milestone by claiming an ITF title in Dunakeszi (Hungary) without losing a single set, becoming the youngest Ukrainian to win a professional singles tournament. Her doubles prowess was also evident, as she partnered with Olga Danilovic to win the girls’ doubles championship at the US Open in September. Capping off the year, she triumphed at the ITF Junior Masters in Chengdu, China, and attained a career-high junior ranking of world No. 2 on October 30, 2017.
Marta Kostyuk made her debut at a Grand Slam main draw during the 2018 Australian Open as a wildcard entry into the qualifiers. Her breakthrough was historic; she became the first player born in 2002 to reach this level. After defeating Arina Rodionova, Daniela Seguel, and Barbora Krejcikova in qualifying rounds, she stunned Peng Shuai in the first round to become Melbourne’s youngest match winner since Martina Hingis in 1996. Her momentum continued with a win over Australian wildcard Olivia Rogowska, making her the youngest player since Mirjana Lucic-Baroni in 1997 to advance to the third round of a major tournament. Although her journey ended against fourth-seed Elina Svitolina, her performance gained widespread recognition.
Building on her success, Marta Kostyuk captured the Burnie International title in Australia—an ITF $60k event—in February 2018 and later reached the final of another $60k tournament in Zhuhai in March. However, her progress slowed as the year concluded without further significant achievements.
In 2019, she added two more ITF circuit titles to her resume and reached the quarterfinals of the Strasbourg WTA event as a qualifier before losing to Caroline Garcia. Despite showing promise throughout the season, she finished ranked No. 155.
Her upward trajectory resumed in February 2020 with victory at the $60k Cairo Open in both singles and doubles (alongside Kamilla Rakhimova). Following months of interruption due to COVID-19, Marta Kostyuk participated in events like the Palermo Ladies Open and Prague Open, showcasing determination through qualifiers to enter main draws. At the US Open later that year, she delivered impressive wins against seasoned players such as former top-10 Daria Kasatkina and 31st seed Anastasija Sevastova. Although her run was halted by Naomi Osaka in an intense third-round clash after pushing the former champion to three competitive sets, Marta Kostyuk proved herself as a formidable talent on large stages.
Her story reflects resilience, early excellence, and an upward arc of achievements that mark her as one of tennis’s emerging stars.
In 2021, during the WTA 500 Abu Dhabi Open, Marta Kostyuk advanced to the semifinals with victories over Lucie Hradecká, Hsieh Su-wei, Tamara Zidansek, and Sara Sorribes Tormo.

At the onset of the 2024 clay-court season, Marta Kostyuk demonstrated remarkable resilience at the WTA 500 Stuttgart Grand Prix. She began her campaign by defeating local wildcard Laura Siegemund and fifth seed Zheng Qinwen, saving five match points in the process to secure her place in the quarterfinals. Building on this momentum, she overcame third seed Coco Gauff on her eighth match point, earning her career’s first victory over a top-3 player and advancing to the semifinals. Marta Kostyuk then continued her streak with a straight-sets win against sixth seed and Grand Slam champion Marketa Vondrousova, marking her third top-10 triumph in as many days and securing a spot in her second WTA 500 final. However, her impressive run ended in the final, where she fell to Elena Rybakina in straight sets.
Moving to the French Open, Marta Kostyuk reached the second round in singles but was defeated by Donna Vekic. In doubles, she achieved a significant milestone by reaching the semifinals for the first time at this Grand Slam. Partnering with Elena-Gabriela Ruse, the duo secured wins over ninth seeds Leylah Fernandez and Erin Routliffe, followed by a walkover victory against Mirra Andreeva and Vera Zvonareva.
Later in 2024, Marta Kostyuk teamed up with Dayana Yastremska to represent Ukraine at the Paris Olympics. Despite their efforts, they exited in the second round after falling to Taiwanese team Hsieh Su-wei and Tsao Chia-yi.
In February 2025, Marta Kostyuk delivered another standout performance at the WTA 1000 Qatar Open. She defeated Zeynep Sonmez, world number three Coco Gauff, and Magda Linette to reach the quarterfinals but narrowly lost to Amanda Anisimova after a hard-fought three-set encounter.

At the Canadian Open, Marta Kostyuk capitalized on her 24th seed status with a first-round bye. She then defeated Marketa Vondrousova, 15th seed Karolina Muchova, and 28th seed McCartney Kessler to secure her third WTA 1000 quarterfinal appearance of the year. Unfortunately, her run came to an abrupt end in the match against ninth seed Elena Rybakina when a wrist injury forced her to retire in the second set after dropping the first.
