2026 French Open – Women's singles

Mirra Andreeva defeated Maja Chwalińska in the final, 6–3, 6–2 to win the women's singles tennis title at the 2026 French Open. It was her first major title. Andreeva was the youngest woman (19 years and 1 month) to win the tournament since Monica Seles in 1992. Chwalińska was the second qualifier in the Open Era to reach a major final, after Emma Raducanu at the 2021 US Open. She was the third woman to reach the French Open final on her tournament debut, after Evonne Goolagong in 1971 and Chris Evert in 1973. She was also the third Polish major finalist in the Open Era, following Agnieszka Radwańska and Iga Świątek. Ranked No. 114, Chwalińska became the lowest-ranked finalist in French Open history.

Coco Gauff was the defending champion, but lost in the third round to Anastasia Potapova. This was the first time since 2021 that Gauff was ousted from the French Open by someone other than Iga Świątek.

Marta Kostyuk became the first Ukrainian woman to reach the semifinals at the French Open, defeating compatriot Elina Svitolina in the first all-Ukrainian major quarterfinal in the Open Era. She was the third Ukrainian major semifinalist in the Open Era, after Svitolina and Dayana Yastremska. With her third-round win, Sorana Cîrstea became the oldest woman, at 36 years, 52 days old, in the Open Era to score a double bagel in a singles major main-draw match, overtaking Victoria Azarenka from the previous year. By reaching the quarterfinals for the first time since 2009, Cîrstea set the longest gap between a player's first two quarterfinals at a women's singles major in the Open Era.

Aryna Sabalenka retained the world No. 1 singles ranking after Elena Rybakina lost in the second round. Her loss to Diana Shnaider in the quarterfinals guaranteed a first-time major champion. This was the first major since the 1977 French Open to have no former major champions reach the semifinals of either the women's or the men's singles events.
