The 1978–79Quebec Nordiques season was the Nordiques' seventh season in the WHA, were coming off of a 40-37-3 record in the 1977–78 season and a loss in the playoff semi-finals. The Nordiques improved to 41–34–5 to qualify for the playoffs, but lost in the first round to eventual Avco Cup champions Winnipeg Jets.
The Nordiques would start the season slowly, going winless in their opening five games, however, the team snapped out of their slump, winning ten of their next thirteen games to push themselves over the .500 mark. Quebec would stay consistent throughout the season, easily clinching a playoff berth, as the Nordiques would finish the season with a 41-34-5 record, finishing second in the league behind the Edmonton Oilers, who had eleven more points than Quebec.
Offensively, Quebec was led by Real Cloutier, who won the Bill Hunter Trophy by earning a league high 129 points. It was the fourth year in a row that a player from the Nordiques (Marc Tardif in 1976 and 1978, and Cloutier in 1977) would win that award. Cloutier scored a team record 75 goals, and added 54 assists. Marc Tardif had another solid season, scoring 41 goals and 96 points, while Serge Bernier added 36 goals and 82 points. Rich Leduc joined the 30 goal club, as he registered 30 goals and 62 points. On defense, Paul Baxter led the way, scoring 10 goals and 46 points, as well as a team high 240 PIM. Forty-year-old J. C. Tremblay had a productive year, earning 44 points in 56 games.
In goal, Richard Brodeur and Jim Corsi split the action, with Brodeur winning a team high 25 games, as well as a club best 3.11 GAA. Corsi had 16 victories and a 3.30 GAA, while both goaltenders earned three shutouts.
In the opening round of the playoffs, Quebec would face the Winnipeg Jets in a best of seven semi-final series. The Jets finished the season with a 39-35-6 record, earning 84 points, and a third-place finish. The series opened with two games in Quebec, however, the Jets struck first, easily dominating the Nordiques in the series opener, by winning the game 6-3, before crushing Quebec in the second game 9-2 to take a two-game series lead. The series moved to Winnipeg for the next two games, and the Jets would stay hot, as they continued to dominate the Nordiques in the third and fourth games of the series, winning them 9-5 and 6-2 respectively to sweep Quebec out of the playoffs.
