The 1941–42 NHL season was the 25th season of the National Hockey League. Seven teams played 48 games each. The Toronto Maple Leafs would win the Stanley Cup defeating the Detroit Red Wings winning four straight after losing the first three in a best-of-seven series, a feat only repeated three times in NHL history (1975, 2010, 2014) and once in Major League Baseball (2004) as of 2017.
