The 1921 U.S. Open was the 25th U.S. Open, held July 21–22 at Columbia Country Club in Chevy Chase, Maryland, a suburb northwest of Washington, D.C.. Jim Barnes won his only U.S. Open, nine strokes ahead of runners-up Walter Hagen and Fred McLeod, both former champions. It was the third of Barnes' four major championships. Chick Evans, the 1916 champion, edged 19-year-old Bobby Jones by a single stroke for low amateur, finishing alone in fourth place. Two-time champion Alex Smith played in his last major and finished in a tie for fifth place.
