David John Semenko (July 12, 1957 – June 29, 2017) was a Canadian professional ice hockey player, coach, scout, and colour commentator.

During his National Hockey League (NHL) career, Semenko played for the Edmonton Oilers, Hartford Whalers and Toronto Maple Leafs as an enforcer.

He was also the last player to score a goal in the World Hockey Association (WHA) before it folded and merged with the NHL.
