The 1949 U.S. Open was the 49th U.S. Open, held June 9–11 at Medinah Country Club in Medinah, Illinois, a suburb northwest of Chicago. Cary Middlecoff won the first of his two U.S. Open titles, one stroke ahead of runners-up Clayton Heafner and Sam Snead. For Snead, it was the third of four second-place finishes at the only major championship he never won. Middlecoff, a dentist, won his second U.S. Open in 1956.
