The American Hockey League is a 30-team professional ice hockey league based in the United States and Canada that serves as the primary developmental circuit for the National Hockey League. Since the 2010–11 season, every team in the league had an affiliation agreement with an NHL team; in the past, one or two NHL teams would not have an AHL affiliate and so assigned players 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 of the NHL. The current champions are the Grand Rapids Griffins.
