The 1979–80 NHL season was the 63rd season of the National Hockey League. This season saw the addition of four teams from the disbanded World Hockey Association as expansion franchises. The Edmonton Oilers, Winnipeg Jets, New England Whalers (later renamed "Hartford Whalers" at the insistence of the Boston Bruins), and Quebec Nordiques joined the NHL, bringing the total to 21 teams. The other two WHA teams (Birmingham Bulls and Cincinnati Stingers) were paid to disband.
