The 1979–80 NHL season was the 63rd season of the National Hockey League. Twenty-one teams each played 80 games. This season saw the addition of four teams from the collapse of the World Hockey Association (WHA) the previous season as expansion teams. 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 a new total of 21 teams. The other two WHA teams (Birmingham Bulls and Cincinnati Stingers) were paid to disband.
