Martin St. Louis (born June 18, 1975) is a Canadian professional ice hockey right winger and alternate captain currently playing for the Tampa Bay Lightning of the National Hockey League (NHL).
As an amateur, St. Louis played for the University of Vermont Catamounts on the same team as Boston Bruins goaltender Tim Thomas, and on the same line as former Tampa Bay Lightning teammate Éric Perrin. St. Louis was an NCAA all-star and three-time Hobey Baker Award finalist for college player of the year. He ranks first amongst all Vermont scorers in career points (267) and assists (176), and ranks third in career goals (91). Despite his impressive numbers with the Catamounts, he was not drafted. St. Louis was signed by Calgary in 1998. He spent the latter part of the 1997–98 season with the IHL's Cleveland Lumberjacks at the time of his signing with Calgary. He did put up impressive numbers with the Saint John Flames of the American Hockey League (AHL). When Craig Button was appointed GM of the Flames, he released St. Louis who then signed with the Tampa Bay Lightning.
St. Louis was on pace to have a career year in the 2001–02 when his season ended prematurely due to a broken leg. In 2003–04 he led the NHL in scoring with 94 points. He scored an overtime goal in Game 6 of the Stanley Cup Finals, helping the Tampa Bay Lightning defeat the Calgary Flames for the Stanley Cup. At season's end he won both the Hart Memorial Trophy as the most valuable player to his team and the Lester B. Pearson Award as league MVP voted by his peers. St. Louis became the first player since Wayne Gretzky and only the eighth in NHL history, to win the Art Ross Trophy, the Stanley Cup, and the Hart Memorial Trophy all in one season.
