George Martin Lott (October 16, 1906 – December 3, 1991) was an American tennis player and tennis coach who was born in Springfield, Illinois, United States. Lott is mostly remembered as being one of the greatest doubles players of all time. He won the U.S. title five times with three different partners: John Hennessey in 1928; John Doeg in 1929 and 1930; and Les Stoefen in 1933 and 1934. In 1934 Lott became a touring professional, thereby giving up his amateur status and the ability to play in Grand Slam tournaments. In 1929 and 1930 he was ranked World No. 6 and No. 7 by A Wallis Myers; No. 6 by Pierre Gillon in 1930; and in 1931 was ranked No. 4 by Züricher Sport.
