1979 Stanley Cup playoffs

The 1979 Stanley Cup playoffs, the playoff tournament of the National Hockey League, (NHL) began on April 10, after the conclusion of the 1978–79 NHL season. The playoffs concluded on May 21, with the three-time defending champion Montreal Canadiens defeating the New York Rangers 4–1 to win the final series four games to one for the Stanley Cup. Three Original Six teams made the semifinals, which would not happen again until the 2014 Conference Finals.

Playoff bracket
The four division winners earned a bye to the Quarterfinals, while the other eight teams competed first in the Preliminary Round. 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.

Each series in the Preliminary Round was played in a best-of-three format while each series in the other three rounds were played in a best-of-seven format.

(1) Philadelphia Flyers vs. (8) Vancouver Canucks
This was the first playoff series meeting between these two teams.

(2) New York Rangers vs. (7) Los Angeles Kings
This was the first playoff series meeting between these two teams.

(3) Atlanta Flames vs. (6) Toronto Maple Leafs
This was the first playoff series meeting between these two teams.

(4) Buffalo Sabres vs. (5) Pittsburgh Penguins
This was the first playoff series meeting between these two teams.

(1) New York Islanders vs. (8) Chicago Black Hawks
This was the second playoff series meeting between these two teams. New York won the only previous meeting in a two-game sweep in the 1977 Preliminary Round.

(2) Montreal Canadiens vs. (7) Toronto Maple Leafs
This was the fifteenth playoff meeting between these two teams; with the teams splitting the fourteen previous series. They met in previous year's Stanley Cup Semifinals, which Montreal won in a four-game sweep.

These teams did not meet again in the playoffs until 2021.

(3) Boston Bruins vs. (6) Pittsburgh Penguins
This was the first playoff series meeting between these two teams.

(4) Philadelphia Flyers vs. (5) New York Rangers
This was the second playoff series meeting between these two teams. Philadelphia won the only previous meeting in seven games in the 1974 Stanley Cup Semifinals.

(1) New York Islanders vs. (4) New York Rangers
This was the second playoff series meeting between these two teams. The Islanders won the only previous meeting 2–1 in the 1975 Preliminary Round.

(2) Montreal Canadiens vs. (3) Boston Bruins
This was the 18th playoff series meeting between these two teams, which Montreal led 15–2 in previous meetings. This series served as the final chapter in this rivalry for the late 1970s following Montreal's Cup Finals victories over Boston in 1977 and 1978 in four and six games respectively.

This series is best remembered for its dramatic conclusion in the late stages of game seven. Boston's Rick Middleton scored the go-ahead goal with four minutes remaining in regulation. Montreal's dynasty and success over Boston in the playoffs were suddenly in serious jeopardy. However, with time winding down to less than three minutes remaining, Boston committed a series-defining penalty for having too many men on the ice. With Montreal on the power play, Guy Lafleur scored the game-tying goal with 1:14 remaining to force overtime. Approaching the midway point of the first overtime, Yvon Lambert would score the series-winning goal to send the Canadiens to the Stanley Cup Finals for the fourth straight year. This marked the 14th straight playoff meeting between the two teams that ended with the Canadiens defeating the Bruins.

Stanley Cup Finals
This was the 12th playoff series (and only Finals) meeting between these two teams. New York led 6–5 in previous meetings. Their last encounter was won by New York in six games in the 1974 Stanley Cup Quarterfinals.

Prior to 2013, this was the last time two Original Six clubs met in the finals. Both teams would next appear in the Stanley Cup Finals as follows: Canadiens winning in and, Rangers winning in.
