2004 French Open – Women's singles

Anastasia Myskina defeated Elena Dementieva in the final, 6–1, 6–2 to win the women's singles tennis title at the 2004 French Open. It was her first and only major title, becoming the first Russian woman to win a singles major. Myskina saved a match point en route to the title, in the fourth round against Svetlana Kuznetsova. This marked the first major final contested by two first-time finalists since the 1979 Australian Open. The final also made Russia the fourth country in the Open Era (following Australia, the United States, and Belgium) to have two countrywomen contest a major final.

Justine Henin-Hardenne was the defending champion, but lost in the second round to Tathiana Garbin. This was her only loss at the French Open between 2003 and 2007.

Martina Navratilova played in her first singles major since the 1994 Wimbledon Championships, being unseeded for the first time since the 1973 US Open. Awarded a wild card, she made her final French Open singles appearance; she lost in the first round to Gisela Dulko.
