The 1957 U.S. Women's Open was the twelfth U.S. Women's Open, held June 27–29 at the East Course of Winged Foot Golf Club in Mamaroneck, New York.

It was the fifth conducted by the United States Golf Association (USGA).

Betsy Rawls won when the apparent champion, Jackie Pung[3] at 6-over par 298, was disqualified for signing an incorrect scorecard.

Pung made exactly the same error on Jameson's card, who was also disqualified.

[4][5][6] It was the fourth of eight major championships for Rawls and the third of four U.S. Women's Opens.
