1989 French Open – Women's singles

Arantxa Sánchez Vicario defeated the two-time defending champion Steffi Graf in the final, 7–6(8–6), 3–6, 7–5 to win the women's singles tennis title at the 1989 French Open. This ended Graf's streak of major singles titles at five, and was the only loss she suffered at the majors in the 1989 season. Graf served for the championship at 5–3 in the third set, but lost the game to love and won only three more points from that point. Sánchez Vicario was just 17 years old at the time, and it was the first of her three French Open titles (followed by 1994 and 1998).

This tournament marked the major debut for future world No. 1 Monica Seles, who reached the semifinals before losing to Graf. It was also the first French Open since 1978 not to feature Martina Navratilova or Chris Evert.
