1973 US Open – Women's singles

Margaret Court defeated Evonne Goolagong in the final, 7–6, 5–7, 6–2 to win the women's singles tennis title at the 1973 US Open. It was her fifth US Open singles title and record-extending 24th and last women's singles major title, an all-time record that still stands.

Billie Jean King was the two-time defending champion, but lost in the third round to Julie Heldman.

This marked the first time a major offered equal prize money to both men and women. It would take several decades for the other three majors would follow suit, the Australian Open in 2001 and Wimbledon Championships and French Open in 2007.
