Doris Hart (June 20, 1925 – May 29, 2015) was an American tennis player who was active in the 1940s and first half of the 1950s.

Hart reached 67 Grand Slam finals and won 35 titles, tying with Louise Brough for sixth on the all-time list (behind Margaret Smith Court (64), Martina Navratilova (59), Billie Jean King (39), Serena Williams (39), and Margaret Osborne duPont (37)).

She started playing tennis when she was 10 years old, greatly encouraged by her brother Bud.

[3][4] Her first Grand Slam singles title came at the 1949 Australian National Championships, where she was the only non-Australian player in the draw.

[1] Hart did not lose a Grand Slam women's doubles match from the 1951 French International Championships through the semifinals of the 1954 Wimbledon Championships, 43 matches in total, although she skipped 4 Grand Slam tournaments during this period.

She (and partner Stan Smith) lost in the third round of the 1968 Wimbledon Championships to Frew McMillan and Annette Van Zyl Du Plooy 6–3, 12–10.

[7] Hart was included in the year-end top 10 rankings issued by the United States Lawn Tennis Association from 1942 through 1955.
