John Thomas Godfray Hope Doeg (December 7, 1908 – April 27, 1978) was a male tennis player from the United States. In August 1929 Doeg won the singles title at the Seabright Invitational defeating Richard Norris Williams in three straight sets. About a year later, he fulfilled his promise and won his first and only major singles tournament, the 1930 U.S. National Championships at Forest Hills, defeating Frank Hunter in the quarterfinals, Bill Tilden in the semifinals and Frank Shields in the final in four sets. He proceeded to reach a career-high singles world ranking of No. 4 in the same year.
