Billie Jean King defeated Evonne Goolagong in the final, 3–6, 6–3, 7–5 to win the women's singles tennis title at the 1974 US Open. It was her fourth US Open singles title. Goolagong was attempting to complete the career Grand Slam. Margaret Court was the reigning champion, but did not compete this year. Chris Evert held a 55-match winning streak before being defeated by Goolagong in the semifinals. This was an Open Era record streak length until 1984, when it was surpassed by Martina Navratilova. This was the last edition of the tournament to be held on grass courts, as it would switch to clay the following year.
