1931 Wimbledon Championships – Men's singles

Sidney Wood was declared winner of the title by default over Frank Shields in capturing the gentlemen's singles tennis title at the 1931 Wimbledon Championships. Shields withdrew due to a knee injury sustained during his semi-final match against Jean Borotra. This made Wood the only player in the title's history to win without having to compete in the final. Bill Tilden was the defending champion, but did not compete.
