The women's international team competition now called the Billie Jean King Cup was known as the Fed Cup until 2020.
The competition began in 1963 as the Federation Cup, created by the International Tennis Federation to mark its 50th anniversary. The inaugural event featured 16 nations and was held at Queen's Club in London, with the United States defeating Australia in the final.
The name was shortened to the Fed Cup in 1995, the same year the competition adopted a home-and-away format modeled partly on the men's Davis Cup. In September 2020, the event was renamed the Billie Jean King Cup to honor the American champion and equality advocate.
A common mix-up is confusing the Fed Cup with the Davis Cup: the Davis Cup is the men's equivalent. The Wightman Cup was an earlier women's team contest between the United States and Great Britain, while the Hopman Cup is a mixed-team event involving men and women.
