Tennis at the 1900 Summer Olympics – Men's singles

This was the second appearance of the men's singles tennis. The event has been held at every Summer Olympics where tennis has been on the program: from 1896 to 1924 and then from 1988 to the current program. Demonstration events were held in 1968 and 1984.

The Doherty brothers of Great Britain were heavily favored.[1] Reginald Doherty had just won his fourth straight The Championships, Wimbledon singles title. Laurence Doherty would later win five (1902–1906). Their strongest competition was likely Harold Mahony, who had won Wimbledon in 1896 and the European championship in 1899. Max Decugis was the strongest non-British player (and would win 8 French championships after the Games), but he withdrew; André Prévost was the 1900 French runner-up.

The United States made its debut in the event. France and Great Britain both made their second appearance.

The competition was a single-elimination tournament with no bronze medal match (both semifinal losers tied for third). All matches before the final were best-of-three sets; the final was best-of-five sets.
