The 1978–79 WHL season was the 13th season of the Western Hockey League (WHL), and the first under that shortened name after previously operating as the Western Canada Hockey League. The season featured twelve teams and a 72-game regular season. The Brandon Wheat Kings secured their third consecutive regular season title, posting the league's best record—accumulating a league record 125 points in the standings—and followed the title up with the team's first playoff championship, defeating the Portland Winter Hawks in the final series to capture the President's Cup. The season was the first—and only—season for the second incarnation of the Edmonton Oil Kings after the Flin Flon Bombers relocated to Edmonton prior to the season.
