Barbora Krejčíková and Kateřina Siniaková defeated Bethanie Mattek-Sands and Iga Świątek in the final, 6–4, 6–2 to win the women's doubles tennis title at the 2021 French Open. It was their second French Open title and third major title together. Krejčíková became the first woman to win both the singles and doubles tournaments at a major since Serena Williams at the 2016 Wimbledon Championships, and the first to do so at the French Open since Mary Pierce in 2000, making her the seventh woman to accomplish the sweep in French Open history.{{Cite news |last=Petrequin |first=Samuel |date=13 June 2021 |title=Krejcikova completes titles sweep in Paris with Siniakova |work=Associated Press |url=https://apnews.com/article/europe-paris-french-open-tennis-sports-e923d59dd21cb7a2a01a9b65c48530bf |access-date=6 December 2021 |archive-url=https://web.archive.org/web/20210613170118/https://apnews.com/article/europe-paris-french-open-tennis-sports-e923d59dd21cb7a2a01a9b65c48530bf |archive-date=13 June 2021}} Mattek-Sands and Świątek reached the final after saving seven match points in their third round match against Hsieh Su-wei and Elise Mertens.
By winning the title, Krejčíková also reclaimed the world No. 1 doubles ranking. Kristina Mladenovic and Hsieh Su-wei were both in contention for the ranking, but Mladenovic did not participate and Hsieh lost in the third round.
