The 1931 U.S. Open was the 35th U.S. Open, held July 2–6 at Inverness Club in Toledo, Ohio. Billy Burke won his only major title, defeating George Von Elm in a marathon 72-hole playoff, the longest in tournament history. Von Elm, the 1926 U.S. Amateur champion, held the 54-hole lead at 217 after rounds of 75-69-73. Burke, playing just ahead of Von Elm in the final round, carded a 73 and a 292 total. Von Elm bogeyed 12, 14, 15, and 16, and needed a birdie at 18 to force a 36-hole playoff on Sunday.
