Wills entered the singles and doubles competitions at the 1924 Olympics in Paris, France. The tennis tournament was played on outdoor clay courts at the Stade Olympique Yves-du-Manoir in Colombes, a northwestern suburb of Paris. It was the last Olympics where tennis was a medal event until the sport returned at the 1988 Olympics in Seoul, South Korea. Wills won the Olympic gold medal in both the singles and doubles events. In the singles event she had a bye in the first round and won her next four matches in straight sets to reach the final which was played on July 19. Her opponent in the final was Julie Vlasto of France who was defeated in two sets. In the doubles event she partnered veteran Hazel Wightman. The team reached the semifinal without playing, after a bye in the first round followed by two walkovers. The final against Covell and McKane was a repeat of the Wimbledon final and again the result was a two-sets victory for Wightman and Wills. In early August she returned to the United States to compete in the U.S. Championships. For the first time in her career she won all three titles in the singles, doubles and mixed doubles events. For the third successive year she played against Mallory in the singles final and like in 1923 won in straight sets. The mixed doubles event was played at the Longwood Cricket Club in Brookline where she partnered Vinnie Richards to win the final against Mallory and Tilden. In September she won the California State Championships against May Sutton in the final. She was again ranked No. 3 in the world behind Lenglen and McKane by A. Wallis Myers.
