The cup is named after Frank Calder, who was the first president of the National Hockey League. The Calder Memorial Trophy, which is awarded annually to the Rookie of the Year in the National Hockey League, was also named after Calder.
The Hershey Bears and the original Cleveland Barons are tied for the most Calder Cup championships with nine; the Springfield Indians/Kings are third with seven. Eight teams have won back-to-back championships; the Springfield Indians of 1960-62 is the only team to have won three straight Calder Cup championships.
On three occasions an AHL club has won the Calder Cup and its NHL affiliate also won the Stanley Cup. In both 1976 and 1977 the Montreal Canadiens and affiliates Nova Scotia Voyageurs won both trophies. In 1995, the New Jersey Devils and Albany River Rats achieved the same feat.
The playoff MVP is awarded the Jack A. Butterfield Trophy. The current Calder Cup champions are the Chicago Wolves.
