1919 Stanley Cup playoffs
The 1919 Stanley Cup playoffs was an ice hockey tournament held at the conclusion of the 1918–19 season. It was played from February 22 to March 29 for the Stanley Cup. The finals, between the National Hockey League champion Montreal Canadiens and the Pacific Coast Hockey Association champion Seattle Metropolitans, ended after five games due to the Spanish flu outbreak, with the teams tied at two wins each with one tie. After the series, the Canadiens' manager attempted to award the Cup to Seattle, but the Seattle team refused it; both teams' names are engraved on the Cup as co-champions. It was the only time in the history of the Stanley Cup that it was not awarded due to a no-decision after playoffs were held.

The 1918–19 NHL season began with three teams, but the season ended early with the Toronto Arenas suspending operations. This left the Montreal Canadiens and Ottawa Senators – coincidentally the two teams leading each half of the season – to play off for the championship. Montreal won the best-of-seven series, four games to one.PCHA Championship
