National Hockey League

The National Hockey League (NHL; French: Ligue nationale de hockey [liɡ nɑsjɔnal də ɔkɛ], LNH) is a professional ice hockey league in North America composed of 32 teams, 25 in the United States and 7 in Canada. The NHL is one of the major professional sports leagues in the United States and Canada and is considered the premier professional ice hockey league in the world. 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 International Ice Hockey Federation (IIHF) views the Stanley Cup as one of the "most important championships available to the sport". The league's headquarters have been in New York City since 1989, when it moved from Montreal; the league also has offices in Toronto and Montreal.

The NHL 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 at Renfrew, Ontario. The NHL immediately took the NHA's place as one of the leagues that contested for the Stanley Cup in an annual interleague competition, before a series of league mergers and foldings left the NHL as the only league competing for the Stanley Cup in 1926.
