The Bellingham Mariners were a minor league baseball team that represented Bellingham, Washington, in the Class A short-season Northwest League. The franchise was affiliated with the Los Angeles Dodgers from 1973–76 (during which time they were called the Bellingham Dodgers), the Seattle Mariners from 1977–94 (in which they took the name they held the longest, the Bellingham Mariners, or the "Baby M's" as they were popularly known), and the San Francisco Giants from 1995-96 (they became the Bellingham Giants for those two seasons) before they moved to Keizer, Oregon and became the Salem-Keizer Volcanoes.
In 1987, 17-year-old Ken Griffey, Jr. hit his first professional home run while on the road at Everett Memorial Stadium. A plaque was placed on the sidewalk outside the stadium where the ball landed.
The Bellingham franchise played at Joe Martin Field, a stadium with a seating capacity near 1,600. The park is currently the home of the Bellingham Bells of the West Coast Collegiate Baseball League.
The Bellingham Mariners and Everett Giants swapped cities in 1995, and the M's affiliate became the Everett AquaSox.
