Mario Tremblay (born September 2, 1956, in Alma, Quebec) is a former professional ice hockey player and a former National Hockey League head coach.
Tremblay, nicknamed "Le bleuet bionique-The Bionic Blueberry", played with the Montreal Canadiens for his entire NHL playing career (1974 to 1986), and was also the coach of the club from 1995 until his resignation in 1997, winning five Stanley Cup Championships with the team as a player in 1976, 1977, 1978, 1979, 1986. Although his playing days have been overshadowed by his controversial coaching career, it is to be noted that Mario is 10th on the Montreal Canadiens all time list for plus-minus at 184.
He is best known for his long running dispute with star goaltender Patrick Roy, which eventually led to Roy's departure from Montreal. The two had almost come to blows in a Long Island coffee shop before Tremblay was announced as a coach and his first appearance in the dressing room was greeted with snickers from Roy.
