Which tennis star won an incredible 20 Wimbledon titles and 13 U.S. Open titles?

Billie Jean King won 20 Wimbledon titles and 13 U.S. Open titles across singles, doubles, and mixed doubles events. She collected 39 Grand Slam titles overall, making her one of tennis history’s most successful all-around players.

King’s 20 Wimbledon championships included six in singles, 10 in women’s doubles, and four in mixed doubles. Her Wimbledon success spanned 1961 to 1979, including a 1973 “triple crown” when she won the singles, women’s doubles, and mixed doubles titles at the same tournament.

The U.S. Open total is also an all-events figure, not a singles-only record. King won four U.S. Open singles titles, alongside championships in doubles and mixed doubles. She won her final Grand Slam title there in 1980.

A common mix-up is to compare these totals with singles records alone. King’s six Wimbledon singles titles and four U.S. Open singles titles are distinct from her combined totals. Beyond competition, she helped found the Women’s Tennis Association and became a major advocate for equal prize money and women’s rights in sport.
