The American Hockey League (AHL) is a 30-team professional ice hockey league based in the United States and Canada that serves as the primary developmental league for the National Hockey League (NHL). Since the 2010–11 season, every team in the league has an affiliation agreement with one NHL team. When NHL teams do not have an AHL affiliate, players are assigned to AHL teams affiliated with other NHL teams. Twenty-six AHL teams are located in the United States and the remaining four are in Canada. The league offices are located in Springfield, Massachusetts, and its current president is David Andrews. 

The annual playoff champion is awarded the Calder Cup, named for Frank Calder, the first President (1917–1943) of the NHL. The reigning champions are the Grand Rapids Griffins. 

The AHL traces its origins directly to two predecessor professional leagues: the Canadian-American Hockey League (the "Can-Am" League), founded in 1926, and the first International Hockey League, established in 1929. Although the Can-Am League never operated with more than six teams, the departure of the Boston Bruin Cubs after the 1935–36 season reduced it down to just four member clubs – Springfield Indians, Philadelphia Ramblers, Providence Reds, and New Haven Eagles – for the first time in its history. At the same time, the then-rival IHL lost half of its eight members after the 1935–36 season, also leaving it with just four member teams: Buffalo Bisons, Syracuse Stars, Pittsburgh Hornets and Cleveland Falcons.
