The 1983 Open Championship was a men's major golf championship and the 112th Open Championship, held from 14 to 17 July at Royal Birkdale Golf Club in Southport, England. It was the sixth time the course had hosted, with the first in 1954. Defending champion Tom Watson won his fifth Open Championship, one stroke ahead of runners-up Andy Bean and Hale Irwin. It was his second consecutive Open win and third in the last four, but was helped by Irwin "whiffing" a one-inch putt on the 14th hole on the third day, which cost him a chance of a play-off with Watson for the tournament.
