The Seattle Mariners 1994 season was their 18th since the franchise creation, and ended the season finishing third in the American League West, finishing with a .430 record. The season was cut short by the infamous 1994 player's strike, which began on August 12. The Mariners played their final twenty games on the road, due to interior ceiling repairs at the Kingdome; they were 10–1 in August, and won their final six games.
