The 1988–89 WHL season was the 23rd season of the Western Hockey League (WHL), featuring fourteen teams and a 72-game regular season. Less than three years after the 1986 team bus crash that killed four players, the Swift Current Broncos put together the best season in the club's history. The Broncos won their first Scotty Munro Memorial Trophy for the best regular season record, and in the playoffs defeated the Portland Winter Hawks to win their first President's Cup as league champions—the Broncos went undefeated throughout the playoffs. This earned the Broncos a berth in the 1989 Memorial Cup tournament, which was hosted in Saskatoon. At the tournament, the Broncos defeated the host Saskatoon Blades to win the Memorial Cup title.
This was the first season for the Tri-City Americans after the New Westminster Bruins relocated to Kennewick, Washington prior to the season. The Americans became the fourth WHL club based in the United States.
