The 1920 Stanley Cup Finals took place between March 22 and April 1. The National Hockey League (NHL) champion Ottawa Senators defeated the Pacific Coast Hockey Association (PCHA) champion Seattle Metropolitans 3 games to 2 in the best-of-five game series. Although all of the games for the series was scheduled to be played at Dey's Arena in Ottawa, unseasonably warm weather and poor ice conditions forced the last two contests to be played on the artificial ice at Toronto's Arena Gardens (also known as the Mutual Street Arena).
