1998–99 WCHL season

The 1998–99 West Coast Hockey League season was the fourth season of the West Coast Hockey League, a North American minor professional league. Nine teams began the regular season, although the Tucson Gila Monsters folded after 21 games. Tucson's unexpected mid-season exit created schedule irregularities, causing some teams to play 70 regular season games while others played 71.

The Tacoma Sabercats were the league champions.
