The 1989 Seattle Mariners season was their 13th since the franchise creation, and the team finished in sixth place in the American League West division, with a record of 73–89 (.451). The Mariners were led by first-year manager Jim Lefebvre. and

The season was enlivened by the arrival of 19-year-old Ken Griffey Jr., the 1st overall pick of the 1987 Major League Baseball (MLB) draft. The team traded for fellow future Hall of Famer Randy Johnson in May, sending out All-Star Mark Langston.

In August, owner George Argyros sold the team to Jeff Smulyan.
