Timothy Gleason (born January 29, 1983) is an American professional ice hockey defenseman and an alternate captain of the Carolina Hurricanes of the National Hockey League.
After a standout junior career with the Windsor Spitfires, Gleason was drafted in the first round (twenty-third overall) of the 2001 NHL Entry Draft by the Ottawa Senators. Unable to come to terms on a contract with the Senators, Gleason was subsequently traded to the Los Angeles Kings for forward Bryan Smolinski on March 11, 2003. After spending three years in the Kings organization, Gleason (along with Éric Bélanger) was traded to the Hurricanes on September 29, 2006, for defensemen Oleg Tverdovsky and Jack Johnson.
Gleason is known for his toughness and gritty play, including the diving effort to prevent the puck from leaving the offensive zone in Game Seven of the 2009 Eastern Conference Semifinals against the New Jersey Devils, leading to a game-tying goal. He also took a puck to the face against Washington in 2009, but returned to the ice after multiple stitches to score the tying goal on a breakaway.
