Samantha Stosur defeated Serena Williams in the final, 6–2, 6–3 to win the women's singles tennis title at the 2011 US Open.^[1] It was her first and only major singles title. Stosur became the first Australian woman to win a major since Evonne Goolagong Cawley at the 1980 Wimbledon Championships, and the first to win the US Open since Margaret Court in 1973.

Kim Clijsters was the two-time reigning champion, but withdrew due to an abdominal injury.

This was the first time in the tournament's history where no American players were among the top ten seeds.
