The Dominican Summer League Mariners, or DSL Mariners, are a Rookie-level affiliate of the Seattle Mariners that competes in the Dominican Summer League of Minor League Baseball. The team plays its home games in Boca Chica, Dominican Republic.

The Mariners first had a Dominican minor league affiliate in 1989. The team played in San Cristóbal for two seasons, then in Santo Domingo. The Mariners also had a Venezuelan Summer League team from 2002 to 2015. After shuttering its Venezuelan academy in early 2015, the Mariners had a second Dominican team, called DSL Mariners 2, for one season.

The Mariners opened a $7 million training academy in Boca Chica in 2014, after previously sharing a facility with the Los Angeles Dodgers. The academy also helps players earn their equivalent of a high school diploma.
