2009 French Open – Women's singles

Svetlana Kuznetsova defeated Dinara Safina in the final, 6–4, 6–2 to win the women's singles tennis title at the 2009 French Open. It was her second major title, after the 2004 US Open. The final marked the third all-Russian final in major singles history, and the first since the 2004 US Open. It was Safina's third runner-up finish in as many major finals. The match was also the conclusion of a series of finals between the pair during that clay court season, as they each claimed the Stuttgart and Rome titles over each other.

Ana Ivanovic was the defending champion, but lost in the fourth round to Victoria Azarenka.

Sorana Cîrstea became the first player born in the 1990s to reach a major quarterfinal.
