Françoise Dürr (born 25 December 1942; sometimes referred to by English writers as Frankie Durr) is a retired French tennis player.

She is also noted for having an unorthodox serve that "might not have registered on a radar gun" according to her official Tennis Hall of Fame biography.

Françoise Dürr married Boyd Browning, an American radio executive, in 1975 and later moved to the United States where she stayed for 10 years.

This record is shared with Martina Navratilova and Gigi Fernández, who, like Dürr, achieved it with separate partners.

She was the runner-up in women's doubles at Wimbledon in 1965 with Lieffrig, 1968 with Jones, 1970 with Wade, 1972 with Judy Tegart Dalton, and 1973 and 1975 with Stöve.

Dürr and Betty Stöve won the 1979 WTA Tour Championships in doubles against Sue Barker and Ann Kiyomura, beating them 7–6, 7–6 in the final.

She played the French Open ladies doubles event a last time in 1984, reaching the second round and then retired from Grand Slam competition.

Dürr won over 60 major doubles titles in her career with various partners and featured in many more finals and semifinals.

Dürr, Ann Jones, Billie Jean King and Rosemary Casals were the first women to sign professional contracts and organise their own tours at the start of the open era in 1968.

In 1970, Dürr had a commitment to play her French Tennis Nationals and went back to France, which prevented her from signing up with Gladys Heldman's Original 9 like Stöve too.

[5][6] Dürr was a founding member of the Women's Tennis Association in 1973 and became the WTA's secretary with Billie Jean King elected as president.

She received the WTA Tour's Honorary Membership Award in 1988 for her contributions to the founding, development, and direction of women's professional tennis.
