The National Hockey League All-Decade teams were first named during the 2009–10 NHL season, to honor the best performers over the past decade at each position.
A panel of hockey figures, including general managers, league employees, writers, and others selected by the NHL chooses the All-Decade teams at the end of each decade.
Alexander Ovechkin, Sidney Crosby, and Zdeno Chara are the only players to have been named to multiple teams, with Ovechkin the only player named to the First Team twice. The entire 2000s All-Decade First Team, except for the still-active Ovechkin, have been inducted into the Hockey Hall of Fame.
