1982 Stanley Cup playoffs

The 1982 Stanley Cup playoffs, the playoff tournament of the National Hockey League (NHL) began on April 7, after the conclusion of the 1981–82 NHL season. The playoffs concluded on May 16 with the champion New York Islanders defeating the Vancouver Canucks 3–1 to win the final series four games to none and win the Stanley Cup. A new divisional-based playoff structure was adopted, replacing the previous format that seeded teams regardless of division or conference.

The first round of the 1982 playoffs saw three first-place teams (Edmonton, Minnesota, and Montreal) upset by fourth-place teams, a round which featured what is still the greatest comeback in NHL history: The Kings' 6–5 win over Edmonton in game three. After trailing 5–0 after two periods, the Kings scored five third period goals—three in the last 5:22, the final goal coming with only five seconds left in regulation. Los Angeles then scored on a face-off early in overtime, thus completing the "Miracle on Manchester".

The eventual champion New York Islanders nearly capitulated in the first round as well, losing games three and four of their first-round playoff series with Pittsburgh after crushing the Penguins in the first two games. In game five, the Islanders scored twice in the last five minutes to force overtime and then won the series on John Tonelli's goal 6:19 into the extra session. This served as a wake-up call for New York, who lost only two more games the rest of the way on their march to a third straight Stanley Cup. Their Finals opponents, the Vancouver Canucks, finished the regular season with only 77 points, defeating three teams beneath them in the standings (Calgary 75, Los Angeles 63, and Chicago 72) in the much weaker Campbell Conference. This remains the most recent time that the Detroit Red Wings and the Toronto Maple Leafs missed the playoffs in the same season.
