Marcel Bernard Tremblay (July 4, 1915 – March 20, 1980) was a Canadian professional ice hockey right winger. He played 10 games in the National Hockey League for the Montreal Canadiens during the 1938–39 season. The rest of his career, which lasted from 1936 to 1942, was spent in the minor leagues.
Tremblay had played for several years with the senior Flin Flon Bombers when he signed with the Montreal Canadiens organization in 1938. He was assigned to the New Haven Eagles, but played ten games for the Canadiens that season. He returned to New Haven and played with the team until 1942 when a fractured skull ended his season. Tremblay enlisted in the military and did not play professionally again.
He died on March 20, 1980, in Mobile, Alabama, and is buried there.
