John Geoffrey Heath (April 1, 1915 – December 9, 1975) was a Canadian-born American left fielder in Major League Baseball (MLB) who played most of his career for the Cleveland Indians. He was one of the American League's most promising power hitters of the late 1930s and early 1940s, twice led the AL in triples, and batted at least .340 with over 100 runs batted in (RBIs) each time. In 1941 he was selected to his first All-Star Game and that same season became the first player from the American League to become a member of the 20–20–20 club when he hit 20 each of doubles, triples and home runs in the same season. His other All-Star Game selections were in 1943 and 1945.
