The 1977–78 Portland Trail Blazers season was the eighth season of the Portland Trail Blazers in the National Basketball Association (NBA). Fresh off their first NBA Championship win the previous season, the Blazers led the league with a franchise-best 58–24 record, earning a first-round bye in the 1978 NBA Playoffs. However, they were defeated by the eventual Western Conference champion Seattle SuperSonics four games to two. The Blazers eventually eclipsed their franchise-record win total from this season with a 59–23 showing in 1989–90.
