For over 120 years, the Stanley Cup has been awarded as the culmination of a championship hockey season. The NHL provides a comprehensive list of those teams here.
The NHL reported in the book "Stanley Cup Champions" that the first winner of the Stanley Cup was the Montreal Amateur Athletic Association (AAA), champions of the Amateur Hockey Association of Canada for 1893. “Ironically, Lord Stanley never witnessed a championship game nor attended a presentation of his trophy, having returned to his native England during the 1893 season. Nevertheless, the quest for the trophy he donated has become one of the world's most prestigious sporting competitions.”
“Beginning with the 1926–1927 season, the Stanley Cup has been awarded to the NHL's playoff champion.”
