Mark Messier, Canadian ice hockey player, coach, and sportscaster
Mark John Douglas Messier (; born January 18, 1961) is a Canadian former professional ice hockey centre of the National Hockey League (NHL). His playing career in the NHL lasted 25 years (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 was the last former WHA player to be active in professional hockey, and the last active player who had played in the NHL in the 1970s. After his playing career he served as 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 career lists 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. His playoff leadership while in New York, which ended a 54-year Stanley Cup drought in 1994, earned him the nickname "The Messiah", a play on his name. He was also known, over the course of his career, as "The Moose" for his aggression and strength. He twice won the Hart Memorial Trophy as the league's most valuable player, in 1990 and 1992, and in 1984 he won the Conn Smythe Trophy as the most valuable player during the playoffs. He is a 15-time NHL All-Star. In 2007, he was inducted into the Hockey Hall of Fame, in his first year of eligibility. In 2017 Messier was named one of the "100 Greatest NHL Players" in history.On June 30, 2017, he was named an Officer of the Order of Canada by Governor General David Johnston for "contributions to hockey as an outstanding player and captain, and for his leadership in encouraging children to take up the sport."
