1998 French Open – Women's singles

Arantxa Sánchez Vicario defeated Monica Seles in the final, 7–6, 0–6, 6–2 to win the women's singles tennis title at the 1998 French Open. It was her third French Open title and fourth and last major singles title overall, and the last major singles final for both players. This was also the third and the last victory for Sánchez Vicario over Seles in their rivalry.

Iva Majoli was the defending champion, but lost to Lindsay Davenport in the quarterfinals.

This is the most recent edition of the French Open to have a final that was a rematch of a previous edition's final. Both finalists previously met in 1991, which was won by Seles.

Martina Hingis was attempting to complete a non-calendar-year Grand Slam, having won the preceding Wimbledon, US Open, and Australian Open titles, but lost to Seles in the semifinals.

This marked the first French Open singles appearance of future three-time champion, 23-time major winner, Olympic gold medalist and world No. 1 Serena Williams; she lost to Sánchez Vicario in the fourth round.
