The 1974 U.S. Women's Open was the 29th U.S. Women's Open, held July 18–21 at La Grange Country Club in La Grange, Illinois, a suburb west of Chicago.

After a double bogey, Sandra Haynie sank birdie putts from 70 and 15 feet (21 and 5 m) on the final two holes to win by a stroke over runners-up Carol Mann and Beth Stone. Haynie had won the previous major, the LPGA Championship, a month earlier.
