The 1931 Open Championship was the 66th Open Championship, held 3–5 June at Carnoustie Golf Links in Carnoustie, Angus, Scotland. Tommy Armour outlasted José Jurado by a single stroke to win his only Open title, and his third and final major championship. This was the first time Carnoustie hosted the championship. Armour, age 36 and a U.S. citizen, played the Open Championship just once more; he returned to Britain to defend his title in 1932 and finished in 17th place.
