1990 Wimbledon Championships – Women's singles

Martina Navratilova defeated Zina Garrison in the final, 6–4, 6–1 to win the ladies' singles tennis title at the 1990 Wimbledon Championships. It was her record ninth Wimbledon singles title and 18th and last major singles title overall, tying Chris Evert's Open Era record. It was also her ninth consecutive Wimbledon final. For the fourth time in her career, Navratilova did not lose a set during the tournament.

Steffi Graf was the two-time defending champion, but lost in the semifinals to Garrison. This marked the first time since the 1987 Australian Open that Graf did not reach a major final, ending a record stretch of 13 consecutive appearances.

By defeating Monica Seles in the quarterfinals, Garrison ended the former's 36-match winning streak, extending back to Miami earlier that year.
