John "Johnny" Fallon (29 April 1913 – 7 December 1985) was a Scottish professional golfer whose career spanned the years either side of World War II. He was born in Lanark, Scotland. Although never a winner of a major tournament of note, Fallon often contended with high finishes - he lost the final of the 1954 British PGA Matchplay Championship, and was perhaps most unlucky that he missed out on a potential Open Championship that might have been played at St Andrews during the war years. He had placed third there in 1939, and then second in 1955, each time by just a handful of strokes.
