The Seattle Mariners 2005 season was their 29th since the franchise creation, and their second consecutive season finishing at the bottom of the American League West, finishing with a record of 69–93 (.426). They only had one player represented at the 2005 All-Star Game, who was Ichiro Suzuki with his fifth selection for the All-Star Game.
