Monterey–Salinas Transit (MST) is a bus service operating in Monterey County, California. Service is primarily to the greater Monterey and Salinas areas, but extends as far south as Paso Robles and Big Sur and as far north as Watsonville and San Jose.

MST serves many local shopping areas, places of employment, tourist sites, government buildings, and residential neighborhoods.
