- Source: 1980 Stanley Cup playoffs
The 1980 Stanley Cup playoffs, the playoff tournament of the National Hockey League (NHL) began on April 8, after the conclusion of the 1979–80 NHL season. This season saw the addition of four teams from the disbanded World Hockey Association (WHA) as expansion franchises, and thus the playoffs were also expanded from 12 to 16 teams. The expanded playoff format allowed two of those former WHA clubs, the Edmonton Oilers and the Hartford Whalers, to make the playoffs in their first season in the NHL. The Atlanta Flames played their final playoff games before moving to Calgary after the season; the playoffs would eventually return to Atlanta in 2007 when the expansion Atlanta Thrashers made their first postseason appearance.
The playoffs concluded on May 24 when the New York Islanders defeated the Philadelphia Flyers 5–4 to win the final series four games to two and win the Stanley Cup. It was the Islanders' first Stanley Cup win and was the first of four consecutive Stanley Cup wins.
Playoff seeds
With the league expansion from 17 to 21 teams, the playoffs were also expanded, from a 12-team tournament to a 16-team tournament. The sixteen teams were composed of the four divisional champions plus the top 12 finishers of the remaining 17 teams. The 16 qualifying teams were then seeded based on regular season points, with divisional rankings ignored. Division leaders no longer received first round byes. The teams were seeded 1 through 16, with the top team playing the 16th team in the first round, and so on. In subsequent rounds, matchups were similarly arranged, with the top remaining seed against the lowest remaining seed, and so on.
The following sixteen teams qualified for the playoffs:
Philadelphia Flyers, Patrick Division champions, Clarence Campbell Conference regular season champions, NHL regular season champions – 116 points
Buffalo Sabres, Adams Division champions, Prince of Wales Conference regular season champions – 110 points
Montreal Canadiens, Norris Division champions – 107 points
Boston Bruins – 105 points
New York Islanders – 91 points
Minnesota North Stars – 88 points
Chicago Black Hawks, Smythe Division champions – 87 points
New York Rangers – 86 points
Atlanta Flames – 83 points
St. Louis Blues – 80 points
Toronto Maple Leafs – 75 points
Los Angeles Kings – 74 points
Pittsburgh Penguins – 73 points (30 wins)
Hartford Whalers – 73 points (27 wins)
Vancouver Canucks – 70 points
Edmonton Oilers – 69 points
Playoff bracket
The NHL used "re-seeding" instead of a fixed bracket playoff system: in each round, the highest remaining seed was matched against the lowest remaining seed, the second-highest remaining seed played the second-lowest remaining seed, and so forth.
Starting this postseason, each series in the Preliminary Round was expanded from a best-of-three format to a best-of-five format. Each series in the other three rounds remained in a best-of-seven format.
