2015 French Open – Women's singles

Serena Williams defeated Lucie Šafářová in the final, 6–3, 6–7^(2–7), 6–2 to win the women's singles tennis title at the 2015 French Open. It was her third French Open title, 20th major singles title overall, and she completed the triple career Grand Slam in singles with the win. Williams would later describe the victory as the proudest moment in her career; she suffered from influenza during the tournament.

Maria Sharapova was the defending champion, but lost in the fourth round to Šafářová.

2008 champion Ana Ivanovic reached her first major semifinal since winning the title seven years previously; it was also her last major semifinal.
