The Seattle Mariners 1986 season was their tenth since the franchise creation. They were seventh in the American League West with a record of 67–95 (.414), the worst record in the league and second-worst in the majors.

At Boston's Fenway Park on Tuesday, April 29, twenty Mariners were struck out by 23-year-old Roger Clemens to set a new major league record. The game was scoreless through six innings, and the Red Sox won 3–1.
