2021 French Open

The 2021 French Open was a major level tennis tournament played on outdoor clay courts. It was held at the Stade Roland Garros in Paris, France, from 30 May to 13 June 2021, comprising singles, doubles and mixed doubles play. The qualifiers took place from 24 May to 28 May. Junior and wheelchair tournaments also took place. Rafael Nadal was the four-time defending champion in men's singles, and Iga Świątek was the defending champion in women's singles.

It was the 120th edition of the French Open and the second Grand Slam event of 2021. The main singles draws included 16 qualifiers for men and 16 for women out of 128 players in each draw, the last Grand Slam to still have 128 women qualifiers instead of 96 in line with the other three majors.

Novak Djokovic won the men's singles title over Stefanos Tsitsipas in the final, marking his 19th Grand Slam singles title and making him the first male player to win the double career Grand Slam in the Open Era. Barbora Krejčíková won the women's singles title over Anastasia Pavlyuchenkova in the final, claiming her maiden Grand Slam singles title. This was the first time in French Open history that both singles victors were from Slavic-speaking nations, namely Serbia and the Czech Republic.

This was the first edition of the event to have formal night sessions in the schedule, joining a practice already established at the Australian Open and US Open, with one match having a 21:00 local time start time each day.

This was the final Grand Slam to use the advantage set in the final set at singles matches, where it was replaced by final set tiebreaker in future tournaments.

The mixed doubles event returned after a one-year absence, though the draw featured only 16 teams instead of the regular 32.
