1984 Stanley Cup playoffs

The 1984 Stanley Cup playoffs, the playoff tournament of the National Hockey League (NHL) began on April 4, after the conclusion of the 1983–84 NHL season. The playoffs concluded on May 19 with the Edmonton Oilers defeating the four-time defending champion New York Islanders 5–2 to win the Stanley Cup Finals four games to one, the franchise's first Stanley Cup.

Playoff seeds
The 1984 playoffs largely maintained the format used for the previous two seasons. The four teams with the best regular-season records from each of the four divisions secured playoff berths. The division semi-finals saw the first-place club against the fourth-place team, while the other two teams played against each other. The winning clubs then met in the division final. Home-ice advantage for these first two rounds of the playoffs were granted to the team with the better regular-season record. Division winners then met one another in the conference finals.

Leaving behind the coin flip system introduced for the 1982 playoffs, the NHL changed the method by which home-ice advantage is determined for the final two rounds. The higher point total accumulated by teams within a division from contests against teams of the other division in the conference, secured home-ice advantage for the corresponding division champion. Similarly, the higher point total accumulated by teams within a conference from contests against teams of the other conference, secured home-ice advantage for the corresponding conference champion.

This formula resulted in home-ice advantage for the Adams and Smythe division champions in the conference finals and resulted in home-ice advantage for the Wales Conference champion in the Stanley Cup finals.

The sequence of Stanley Cup Finals games was changed for this season. The series opened with two games at the venue of the team with home-ice advantage and then shifted to the opponent's rink for the next three games, including the fifth (if necessary). The series then returned to the initial venue for the final two games (if necessary).
