List of National Hockey League retired numbers

This is a complete list of numbers retired by the National Hockey League (NHL). A retired number is a jersey number that is taken out of circulation by a team as a way of honouring a former member of that team who wore that number.

The first team to retire a number was the Toronto Maple Leafs, which retired Ace Bailey's number 6 on February 14, 1934, prior to an All-Star game organized in his honour.

Currently in the NHL, there are 122 retired numbers, 7 former retirements, and 23 honoured numbers. Most of the numbers retired by the Hartford Whalers and Quebec Nordiques were put back in circulation when those franchises relocated and became the Carolina Hurricanes and Colorado Avalanche, respectively, although the Hurricanes keep Gordie Howe's number 9 unofficially retired. The Arizona Coyotes had a policy of retaining the numbers retired when the franchise was the Winnipeg Jets but reversed it after the Phoenix Coyotes were sold and became the Arizona Coyotes. Honoured numbers are similar to retired numbers, except that they remain available for use by other players. Presently, only the Calgary Flames, and the St. Louis Blues employ this designation. The Philadelphia Flyers have also unofficially retired number 31 in honour of goaltender Pelle Lindbergh since his death in 1985.

Wayne Gretzky's number 99 has been retired league-wide, although the Edmonton Oilers and Los Angeles Kings separately retired Gretzky's number.
