Mark John Douglas Messier is a Canadian former professional ice hockey forward. His playing career in the National Hockey League (NHL) lasted 25 seasons (1979–2004) with the Edmonton Oilers, New York Rangers, and Vancouver Canucks. He also played professionally with the World Hockey Association (WHA)'s Indianapolis Racers and Cincinnati Stingers. He also played a short four-game stint in the original Central Hockey League (CHL) with the Houston Apollos in 1979. He was the last WHA player to be active in professional ice hockey, and the last active player in any of the major North American professional sports leagues to have played in the 1970s. After his playing career, he was special assistant to the president and general manager of the Rangers.
Messier is considered one of the greatest ice hockey players of all time. He is second on the all-time list for playoff points (295) and third for regular season games played (1756) and regular season points (1887). He is a six-time Stanley Cup champion—five with the Oilers and one with the Rangers—and is the only player to captain two teams to Stanley Cup championships.
