1988 Stanley Cup playoffs

The 1988 Stanley Cup playoffs, the playoff tournament of the National Hockey League (NHL), began on April 6, after the conclusion of the 1987–88 NHL season. It concluded on May 26, with the defending champion Edmonton Oilers defeating the Boston Bruins to win their second straight Stanley Cup and fourth in five years.

The Presidents' Trophy winning Calgary Flames had home ice advantage during the playoffs thanks in part to Edmonton's struggles without Wayne Gretzky, who missed 16 games due to injury. The Oilers, who had won the Cup in three of the previous four seasons, were still thought to have a good chance at repeating with Gretzky's return. The clash between the Flames and Oilers in the Smythe Division Final was highly anticipated.

The New Jersey Devils made the playoffs for the first time since their move from Denver, winning in overtime at Chicago Stadium on the season's final day to edge the New York Rangers for the Patrick Division's fourth spot. This was only the second time they made the playoffs including their Colorado and Kansas City days.

The 1988 playoffs most notable moment was the cancellation of game four of the finals in Boston after fog issues, a result of high heat and the subsequent building power outage resulted in the game being canceled outright with the result not counting, yet the league retained player stats from the game. The series would move directly on to Edmonton. Gretzky would go on to set NHL playoff records with 31 assists in 18 games and 13 points in the Stanley Cup Finals.

Playoff bracket
In the division semifinals, the fourth seeded team in each division played against the division winner from their division. The other series matched the second and third place teams from the divisions. The two winning teams from each division's semifinals then met in the division finals. The two division winners of each conference then played in the conference finals. The two conference winners then advanced to the Stanley Cup Finals.

In each round, teams competed in a best-of-seven series following a 2–2–1–1–1 format (scores in the bracket indicate the number of games won in each best-of-seven series). Home ice advantage was awarded to the team that had the better regular season record, and played at home for games one and two (and games five and seven, if necessary); the other team then played at home for games three and four (and game six, if necessary).

An exception to the 2–2–1–1–1 format was made during this year's Stanley Cup Finals after a power outage forced the cancellation of the original game four (see below).

(A1) Montreal Canadiens vs. (A4) Hartford Whalers
This was the third playoff series between these two teams. Montreal won both previous meetings, including their most recent meeting in seven games in the 1986 Adams Division Finals. Montreal was the best team in the Wales Conference during the regular season.

(A2) Boston Bruins vs (A3) Buffalo Sabres
This was the third playoff series between these two teams. Boston won both prior meetings. They last met in the 1983 Adams Division Finals, in which Boston won in seven games.

(P1) New York Islanders vs. (P4) New Jersey Devils
This was the first and to date only playoff series between these two teams. This was the first time that a team representing the state of New Jersey qualified for the Stanley Cup playoffs. This was the first ever playoff series victory for the Scouts/Rockies/Devils franchise. This would be the last playoff series until the 2019 Eastern Conference First Round that the Islanders held home-ice advantage.

(P2) Washington Capitals vs. (P3) Philadelphia Flyers
This was the second playoff series between these two teams. Washington won the only previous meeting in a three-game sweep in the 1984 Patrick Division Semifinals.

Washington overcame a 3–1 series deficit to advance to the Patrick Division Finals for the third time in five years. Game seven ended when Dale Hunter scored at 5:57 of the first overtime period to complete the Capitals' comeback.

(N1) Detroit Red Wings vs. (N4) Toronto Maple Leafs
This was the 22nd playoff series between these two teams. Toronto led 11–10 in previous playoff meetings. This was a rematch of the previous year's Norris Division Finals, which Detroit won in seven games.

Game six in Maple Leaf Gardens was future Hall of Famer Borje Salming's final playoff game in the NHL.

(N2) St. Louis Blues vs. (N3) Chicago Blackhawks
This was the fifth playoff series between the Blackhawks and Blues. Chicago won all four previous meetings, including their most recent meeting 3–1 in the 1983 Norris Division Semifinals.

(S1) Calgary Flames vs. (S4) Los Angeles Kings
This was the third playoff series between these two teams, but the first since the Flames relocated from Atlanta. Los Angeles won both previous meetings, including their most recent meeting 2–1 in the 1977 Preliminary Round.

(S2) Edmonton Oilers vs. (S3) Winnipeg Jets
This was the fifth playoff series between the Jets and Oilers. Edmonton won all four previous meetings. This was a rematch of the previous year's Smythe Division Finals, which Edmonton won in a four-game sweep.

(A1) Montreal Canadiens vs. (A2) Boston Bruins
This was the 23rd playoff series between these two teams. Montreal led 20–2 in previous playoff series meetings. This was the fifth year in a row that these team met in the playoffs. Montreal had defeated Boston in the Division Semifinals the four previous seasons.

This was Boston's first playoff series victory against Montreal since the 1943 Stanley Cup Semifinals. Boston had lost the previous 18 playoff series between these two teams, an NHL record for most consecutive playoff series defeats to one team. This was the first of three consecutive series between these two teams that ended in five games (with the winner of all three series making it to the Stanley Cup Finals).

(P2) Washington Capitals vs. (P4) New Jersey Devils
This was the first playoff series between these two teams.

Patrik Sundstrom's eight-point effort in game three (3 goals, 5 assists) set a new Stanley Cup playoff record for most points in a single game.

(N1) Detroit Red Wings vs. (N2) St. Louis Blues
This was the second playoff series meeting between these two teams. St. Louis won the only previous meeting 3–1 in the 1984 Norris Division Semifinals.

(S1) Calgary Flames vs. (S2) Edmonton Oilers
This was the fourth playoff series meeting between these two teams. Edmonton won two of the previous three meetings. Calgary won the most recent meeting in seven games in the 1986 Smythe Division Finals.

In the Battle of Alberta the Oilers would claim the first sweep of the playoffs. In game two Wayne Gretzky scored the overtime winning goal short-handed.

(A2) Boston Bruins vs. (P4) New Jersey Devils
This was the first playoff meeting between these two teams.

This series featured the infamous confrontation between Devils coach Jim Schoenfeld and referee Don Koharski after Game 3, when, during an argument in the tunnel after the game, Koharski tripped and fell, accusing Schoenfield of pushing him. Schoenfield famously responded, "Good, 'cause you fell you fat pig!" Then, he yelled "Have another doughnut! Have another doughnut!" The incident has since become part of NHL lore.

Schoenfeld was suspended by NHL president John Ziegler for Game 4, but the Devils received an injunction from the New Jersey Supreme Court, allowing Schoenfeld to coach the fourth game. In protest, the officials scheduled to work that game in the Meadlowands refused to take the ice, forcing the NHL to scramble for amateur officials to call the game. The injunction was lifted, the league conducted a proper hearing, Schoenfeld served his suspension during Game 5 in the Boston Garden, and the League officials returned to work.

(S2) Edmonton Oilers vs. (N1) Detroit Red Wings
This was the second playoff meeting between these two teams and was a rematch of the previous year's Clarence Campbell Conference Final which Edmonton won in five games.

Stanley Cup Finals
This was the first Finals meeting between these two teams.

The original Game 4 is well known for the high heat resulting in fog that interfered with the game and a subsequent power outage that caused the game to be canceled at 16:37 of the second period. The game results didn't count, but players were able to retain their stats counting towards their playoff records, as per NHL rules. The series moved on to Edmonton, thus allowing the Oilers to win the Cup at home at Northlands Coliseum and complete the four game sweep.
