Guy Carbonneau (born March 18, 1960) is a Canadian retired professional ice hockey player in the National Hockey League (NHL) and the former head coach of the Montreal Canadiens from 2006 until being fired on March 9, 2009. He is also the president of the Quebec Major Junior Hockey League (QMJHL)'s Chicoutimi Saguenéens. His daughter Anne-Marie married his former Dallas Stars teammate Brenden Morrow in 2002.
Carbonneau was drafted 44th overall in the 1980 NHL Entry Draft by the Montreal Canadiens. His strong play as a defensive forward helped the Canadiens to a Stanley Cup championship in 1986, followed by three Frank J. Selke Trophy wins in 1988, 1989, and 1992. In 1989–90, he was named the captain of the Canadiens, and led them to another Stanley Cup win in 1993. On August 19, 1994, he was traded to the St. Louis Blues in exchange for Jim Montgomery. He played there for one season before moving to the Dallas Stars. He earned his third Stanley Cup ring in 1999 with the Stars, and retired from playing following the 1999–2000 season.
Carbonneau was one of the more popular Canadiens; fans chanted "Guy, Guy, Guy!" whenever he touched the puck, much as they did for Guy Lafleur (with whom Carbonneau played from 1983–85) during his career. He was also one of the most admired Dallas Stars players. He took the ceremonial opening faceoff for the Stars when they played the Canadiens at the last game at the Montreal Forum. He received a standing ovation his last game and, due to a fan petition, his number 21 received a one-year moratorium from being worn the following season.
