The 1998–99 WHL season was the 33rd season of the Western Hockey League (WHL). The season featured eighteen teams and a 72-game season. The Calgary Hitmen won both the Scotty Munro Memorial Trophy for posting the best regular season record and the President's Cup as playoff champions, both for the first time in team history. They thus earned a berth in the 1999 Memorial Cup tournament, where they lost the final to the Ottawa 67's.
