William David Thoms (March 5, 1910 – December 26, 1964) was a Canadian professional ice hockey player who played 548 games in the National Hockey League for the Toronto Maple Leafs, Chicago Black Hawks and Boston Bruins between 1932 and 1945.
Thoms tied Charlie Conacher for the NHL goal-scoring lead in 1935–36; however, Conacher is recognized as the goal-scoring champion due to Conacher's playing fewer games. After his retirement in 1945, Thoms briefly coached the Toronto Marlboros of the Ontario Hockey Association, and died of a heart attack on December 26, 1964.
