The Fed Cup was renamed in 2020 in honor of which tennis player?

The Fed Cup was renamed the Billie Jean King Cup in 2020, honoring American tennis champion and equality advocate Billie Jean King. The International Tennis Federation announced the change in September 2020, recognizing her achievements on court and her long-standing work for gender equality.

The competition began in 1963 as the Federation Cup, created to celebrate the 50th anniversary of the International Tennis Federation. In 1995, its name was shortened to the Fed Cup. The 2020 change therefore marked the event's third major name in its history.

King was a world No. 1 player, a 12-time Grand Slam singles champion, and a key figure in the development of professional women's tennis. She helped establish the Virginia Slims circuit and was one of the founders of the Women's Tennis Association in 1973. She also campaigned for equal opportunities in sport and became a prominent advocate for LGBTQ+ rights.

The renamed cup is the women's team equivalent of the Davis Cup. It remains an international nation-versus-nation competition organized by the ITF.
