The 1982 Seattle Mariners season was their sixth since the franchise creation, and the team finished fourth in the American League West with a record of 76–86 (.469). During their first decade, this was the Mariners' best season, their best previous total was 67 wins in 1979. Slightly past the season's midpoint on July 8, their record was 45–38 (.542), just three games behind division-leading Kansas City. Seattle was at .500 (59–59) on August 17, but then dropped seven straight, and closed the season at home with six consecutive losses.
