Elmer Lach (born January 22, 1918 in Nokomis, Saskatchewan) is a retired Canadian professional ice hockey centre who played 14 seasons for the Montreal Canadiens in the National Hockey League. Lach was the recipient of the Art Ross Trophy in 1948 and the Hart Trophy in 1945. He did lead the NHL in scoring during the 1944-45 season with 80 points, but this was before the creation of the Art Ross Trophy.

Elmer won the Stanley Cup three times in the years 1944, 1946, and 1953.
