U.S. Women's Indoor Championships

The U.S. Women's Indoor Championships, was a national tennis championship for women that was sanctioned by the United States Tennis Association and held 79 times from 1907 through 2001 at various locations and on various surfaces.

Lois Felix holds the record for runners-up in singles (4) while Wightman and Norma Taubele Barber hold the record for runners-up in doubles (5).

[1] The women played periods in New York (1907–1920, 1934–1940, and 1947–1953) and Longwood Courts at Chestnut Hill in Massachusetts (1921–1933, 1941–1946, 1954–1966).

In 1969 and 1970 the tournament remained an amateur event, meaning that players who had turned professional during these years were not allowed to compete.

As Cellular South ended sponsoring the tournament after 2011, the event was renamed Memphis International.
