2005 Wimbledon Championships – Women's singles

Venus Williams defeated Lindsay Davenport in the final, 4–6, 7–6^(7–4), 9–7 to win the ladies' singles tennis title at the 2005 Wimbledon Championships. It was her third Wimbledon singles title and fifth major singles title overall. At two hours and 45 minutes, it was the longest Wimbledon women's final in history. Williams became the first woman in the Open Era, and the first since Helen Wills in 1935, to win the title after saving a championship point. She lost only one set during the tournament, to Davenport in the final — which was a rematch of the 2000 final.

Maria Sharapova was the defending champion, but lost to Venus Williams in the semifinals.

The first week of the tournament was headlined by two major upsets — Justine Henin-Hardenne's first round defeat marked the first time in the Open Era that the reigning French Open champion lost her opening match at Wimbledon, while Serena Williams's loss in the third round was her earliest exit at any major since the 1999 French Open.
