Douglas Robert Gilmour (born June 25, 1963) is a Canadian former professional ice hockey player. He played 20 seasons in the National Hockey League (NHL) for the St. Louis Blues, Calgary Flames, Toronto Maple Leafs, New Jersey Devils, Chicago Blackhawks, Buffalo Sabres and Montreal Canadiens. Gilmour was a seventh round selection, 134th overall, of the Blues at the 1982 NHL Entry Draft and recorded 1,414 points in 1,474 games in the NHL between 1983 and 2003. A two-time All-Star, he was a member of Calgary’s 1989 Stanley Cup championship team and won the Frank J. Selke Trophy as the NHL’s best defensive forward in 1992–93. Internationally, he represented Canada three times during his career and was a member of the nation’s 1987 Canada Cup championship team.
Gilmour was nicknamed “Killer” by a Blues teammate due to his likeness in appearance to serial killer Charles Manson (though others have attributed it to his physical style of play despite his small stature). He played three seasons of junior hockey for the Cornwall Royals where he was a member of their Memorial Cup championship team in 1981. In 1982–83, Gilmour was named the most outstanding player in the Ontario Hockey League (OHL) after he scored 177 points, one of the highest totals in league history. Gilmour returned to the OHL following his playing career as he joined the Kingston Frontenacs as head coach in 2008 and was promoted to general manager in 2011. Gilmour was inducted into the Hockey Hall of Fame and the Ontario Sports Hall of Fame in 2011 and his uniform number 93 is retired by the Toronto Maple Leafs. He also has a division named after him in the FCHL.
