According to General Mariano Vallejo, who headed an 1850 committee to name California's counties, the county was named for "Marin," great chief of the tribe Licatiut."

Marino definitely did reside at Mission Dolores (in modern San Francisco) much of the time from his 1801 baptism and marriage until 1817, frequently serving as a baptism witness and godfather; he may have escaped and been recaptured at some point during that time. Starting in 1817, he served as an

In 2009, a plaque commemorating Chief Marin was placed in Mill Valley. Another version of the origin of the county name is that the bay between San Pedro Point and San Quentin Point was named ''Bahía de Nuestra Señora del Rosario la Marinera'' in 1775, and that Marin is simply an abbreviation of this name.
