The 1954–55 NHL season was the 38th season of the National Hockey League (NHL) which lasted from October 7, 1954 to April 14, 1955.

The Detroit Red Wings were the Stanley Cup champions as they defeated the Montreal Canadiens four games to three in the best-of-seven final series.

The Canadiens were without star forward Maurice Richard, who had been suspended for the playoffs, a suspension which led to the March 17, 1955 "Richard Riot" in Montreal, Quebec, Canada.
