Prior the start of the season, the Colorado Rockies moved to East Rutherford, New Jersey where they were renamed New Jersey Devils, leaving Denver without an NHL franchise until 1995. They were also moved to the Patrick Division, forcing the reluctant Winnipeg Jets to leave the Norris Division and take Colorado's place in the Smythe Division. This would be the last relocation of an NHL team until 1995, and the last time a team would be transferred to a new division until 1993. The period between this move and the adding of the expansion San Jose Sharks in 1991 is the second-longest period of stability in league history, surpassed only by the Original Six era. After the season, the St. Louis Blues were sold to Harry Ornest after the NHL prevented Wild Bill Hunter from purchasing that team and moving it to Saskatoon.
The Boston Bruins led the league in overall points with 110. The defending Stanley Cup champion New York Islanders fell from first overall and finished tied for 6th overall and the high-powered, high offence, Edmonton Oilers tied for second overall. The Oilers set a new record, which they had set the previous year, for most goals in a season with 424 and were led by Wayne Gretzky's 196 points. The Oilers also tied the Boston Bruins' 1970–71 record for most 100-point players in one season as Wayne Gretzky, Glenn Anderson, Jari Kurri, and Mark Messier all scored more than 100 points.
The Washington Capitals qualified for the playoffs for the first time in franchise history.
The top four teams in each division qualified for the playoffs. 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 the division semifinals, teams competed in a best-of-five series. In the other three rounds, teams competed in a best-of-seven series (scores in the bracket indicate the number of games won in each series).
