1982 Seattle Mariners season

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 .460.

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 .540, 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.

Home attendance at the Kingdome was 1.07 million, twelfth in the league; it was the first time over a million in five years, since the debut season of 1977.

This was Rene Lachemann's only full year as manager with Seattle; previously the manager at its Class AAA affiliate in Spokane. He took over the major league club in early May 1981, initially on an interim basis, succeeding Maury Wills. Lachemann signed a three-year contract in October 1981, and another during the season in 1982, then was relieved of his duties in late June 1983.
