Reginald Doherty (14 October 1872 – 29 December 1910) was a British World No. 1 ranked tennis player, and the older brother of tennis player Laurence Doherty. During his career he won four consecutive singles titles at the Wimbledon Championships between 1897 and 1900. Additionally he won eight Wimbledon doubles titles and two doubles titles at the U.S. National Championships, all partnering his brother Laurence.
Doherty represented the British Isles in the prestigious Davis Cup contest from 1902 to 1906. In 1902 he won the doubles match with his brother but lost the final and decisive singles match against American Malcolm Whitman in straight sets. In 1903 he contributed significantly to his team's first Davis Cup title against the United States by winning the doubles match and the decisive singles match. Doherty won the Davis Cup trophy a further three times (1904, 1905, 1906) although in these years he only competed, and won, in the doubles matches.
Doherty died of heart failure and neurasthenia on 29 December 1910 at the age of only 38 at his home in Kensington. He was inducted into the International Tennis Hall of Fame in 1980 together with his brother.
