List of Calder Cup champions
The Calder Cup is the trophy awarded annually to the playoff champion of the American Hockey League. First awarded in the 1937–38 season, it is named after Frank Calder, first president of the National Hockey League. The Calder Cup is distinct from the Calder Memorial Trophy, which is awarded annually to the Rookie of the Year in the National Hockey League.
Teams from 28 different cities have won the Calder Cup. The Hershey Bears have won eleven championships, the most of any team currently in the AHL, and have competed in 23 finals, the most of any team in AHL history, compiling an 11–12 record in the finals. Teams representing Cleveland, Ohio are second, with ten championships, with the Barons franchise, which competed in the league until 1973, won nine titles, and the current iteration, the Cleveland Monsters, winning the tenth in 2016. On May 11, 2020, the AHL cancelled the remainder of the 2019–20 AHL season and the 2020 Calder Cup playoffs due to the COVID-19 pandemic, marking the first time that a Calder Cup champion was not awarded in the trophy's history.
The Most Valuable Player of the playoffs is awarded the Jack A. Butterfield Trophy. It was first awarded in 1984 and is named after the former president of the AHL, Jack Butterfield. The trophy has been won by 34 different players, with none having won it more than once.
