The National Hockey League (NHL) is a professional ice hockey league in North America comprising 32 teams—25 in the United States and 7 in Canada. It is considered to be the premier professional ice hockey league in the world, and is one of the major professional sports leagues in the United States and Canada.

The Stanley Cup, the oldest professional sports trophy in North America, is awarded annually to the league playoff champion at the end of each season.

The National Hockey League was organized at the Windsor Hotel in Montreal on November 26, 1917, after the suspension of operations of its predecessor organization, the National Hockey Association (NHA), which had been founded in 1909 in Renfrew, Ontario.

At its inception, the NHL had four teams, all in Canada, thus the adjective "National" in the league's name. The league expanded to the United States in 1924, when the Boston Bruins joined, and has since consisted of both American and Canadian teams.
