Margaret Court was the two-time reigning champion, but did not participate this year.

This tournament marked the first major in which future world No. 1 and 18-time major singles champion Chris Evert competed in the main draw; she lost to King in the semifinals. Evert, 16 years old at the time, competed in 19 consecutive US Opens until her retirement in 1989, failing to reach the semifinals only twice in that span.
