*As of 2016

_{† - These Stanley Cup titles were won during an interleague tournament including league champions from the National Hockey Association (NHA) (dissolved in 1917 and replaced by the NHL), the Pacific Coast Hockey Association (PCHA), and the Western Canada Hockey League (WCHL). The PCHA and WCHL merged to form the Western Hockey League (WHL) in 1925 only to dissolve a season later. Thus, the NHL became the only league to compete for the Stanley Cup in 1926 and has been the championship trophy for the NHL since.}
