1978 Wimbledon Championships – Women's singles

Martina Navratilova defeated Chris Evert in the final, 2–6, 6–4, 7–5 to win the ladies' singles tennis title at the 1978 Wimbledon Championships. It was her first major singles title, and the first of an eventual 18 major singles titles and a record nine Wimbledon singles titles.

Virginia Wade was the defending champion, but was defeated in the semifinals by Evert.

This was the first time Wimbledon seeded 16 players for the ladies' championship, increasing the number from 12 the previous year. There have been at least 16 seeds in every Championship since that time until 2001 when the tournament started having 32 seeds.
