Maja Ewa Chwalińska (Polish: [ˈmaja xfaˈliɲska] ; born 11 October 2001) is a Polish professional tennis player. She has career-high WTA rankings of No. 21 in singles, achieved on 8 June 2026 and No. 91 in doubles, reached on 9 June 2025. Chwalińska's best result is reaching the final of the 2026 French Open, the first qualifier to achieve the feat at the event.
Chwalińska was born on 11 October 2001 in Miechów to Marcela and Tomasz Chwaliński. Her father is a former miner and electrician while her mother is a receptionist. Chwalińska was raised in Dąbrowa Górnicza, an industrial city in the coal-mining south of Poland. She started playing tennis at the age of 7, inspired by Roger Federer, Rafael Nadal, and Novak Djokovic. Long before her breakthrough on the senior WTA tour, Chwalińska was regarded as one of Poland’s brightest junior talents. Early in her life, Maja became close friends with Iga Świątek. “We’ve known each other since we were 10 years old,” Chwalińska revealed to Roland Garros. They were runners-up in the Australian Open 2017 girls’ doubles and won the European junior doubles titles and helped Poland capture the Junior Fed Cup crown in 2016.
After Chwalińska reached the final at the 2026 French Open, 90,000 concertgoers paid tribute to her at the Silesian Stadium in Chorzów, in southern Poland. Polish pop star Dawid Podsiadło and the Polish crowd sang “Sto lat,” a traditional Polish song wishing her a happy life. Podsiadło, who like Maja comes from Dąbrowa Górnicza, had promised to lead the tribute before the French Open final. When he asked Chwalińska on social media whether he would be allowed to hold the trophy if she won, Chwalińska, who didn't reply until after the match was finished, said that although she had not returned with the championship trophy, she could offer him the silver plate awarded to the runner-up.
She won the European 14-and-under doubles title in 2015 and the 16-and-under doubles title in 2016, both with Iga Świątek. She was a member of the Polish team which won the Junior Fed Cup title in 2016, and she made the final of the 2017 Australian Open junior doubles. She won the 16-and-under singles title six months later. Her highest junior Tennis Europe ranking was No. 6 in August 2017.
Poland hosted the Europe/Africa I Fed Cup pool at Zielona Góra in February. Chwalińska represented her country at senior level for the first time in the tie against Denmark, where she partnered Alicja Rosolska in the doubles. They defeated Maria Jespersen and Hannah Viller Møller, recording her first Fed Cup win. She reached the doubles final of the ITF event in Trnava the following week and the singles semifinals in Altenkirchen the week after. She and Ulrikke Eikeri won the doubles title at the ITF tournament in Sunderland, England.
Chwalińska's first singles ITF title followed in July in Bytom. A week later, she made it two singles titles in a row on the Polish swing of the circuit.
2020–21: Grand Slam tournament qualifying debut
Chwalińska made her qualifying debut at the 2020 Australian Open, where she lost in the first round to Isabella Shinikova. She returned to tournament play in August at the 2020 Prague Open, which had been upgraded to replace the cancelled US Open qualifying competition.
Chwalińska lost to Yuan Yue in the first round of qualifying for the 2021 Australian Open, which was held in Dubai, before reaching the semifinals of a $25k tournament in Grenoble, but aggravated her wrist injury in Altenkirchen the following week and had to withdraw from her first match.
She then went to Argentina for a series of $25k tournaments, but contracted COVID-19 and had to return home, after quarantining without playing a match.
In 2021, at 19 years old, she announced she would be putting her professional career on hold. She revealed she was suffering from severe depression and would be taking time off from the courts to fight the problem. Through a social media post, Chwalińska stated she had been dealing with depression since the end of 2019.
2022–23: Major debut at Wimbledon and first win
Chwalińska qualified for her first main draw at the 2022 Wimbledon Championships, defeating second seed CoCo Vandeweghe in the final round of qualifying. She defeated Kateřina Siniaková for her first singles win.
For her WTA Tour debut outside the majors, Chwalińska was given a wildcard entry into the main draw of the 2022 Poland Open, where she recorded her second tour-level win over Rebeka Masarova. At the 2023 Poland Open, where she also entered as a wildcard, she lost to Laura Siegemund in the first round.
2024–25: WTA 125 singles & doubles titles, top 150
In October 2024, Chwalińska qualified for the main draw at the Mérida Open and defeated Rebecca Marino for her first WTA Tour win on hardcourts, where she lost to top seed Renata Zarazúa.
Partnering with Katarzyna Kawa, Chwalińska won her first WTA 125 doubles title at the 2024 Argentina Open defeating Laura Pigossi and Mayar Sherif in the final, which went to a deciding tiebreak. The following week, she won her first WTA 125 singles title at the MundoTenis Open in Florianópolis, Brazil overcoming Ylena In-Albon in the final in straight sets. Alongside Pigossi, she also won the doubles title, defeating Nicole Fossa Huergo and Valeriya Strakhova in the final.
