Which player is Wimbledon's oldest ladies' singles champion?

Charlotte Cooper is Wimbledon's oldest ladies’ singles champion.

Cooper, later known as Charlotte Cooper Sterry, won her fifth Wimbledon singles title in 1908 at 37 years and 282 days old. She defeated Agnes Morton in the All-Comers’ Final, 6–4, 6–4. Because the defending champion did not return, winning that final secured the championship.

Her record is especially notable because it came after a seven-year gap between her fourth and fifth singles titles. Cooper first won Wimbledon in 1895 and also captured the championships in 1896, 1898 and 1901. She remained a major figure in the early history of women’s tennis.

Cooper was also a pioneer beyond Wimbledon. At the 1900 Paris Olympics, she won the women’s singles and mixed doubles events, becoming the first female Olympic tennis champion and the first individual female Olympic champion. Her age record concerns the ladies’ singles title, not simply reaching a final.
