Marin City is an unincorporated community and census-designated place (CDP) in Marin County, California, United States. It is located 1.5 miles (2.4 km) northwest of downtown Sausalito, and about 5 miles north of San Francisco from the Golden Gate Bridge, at an elevation of 23 feet (7 m). Marin City was developed for housing starting in 1942, to accommodate wartime shipyard workers and other migrants to California. Among those were African Americans from the South in the Great Migration, which continued until 1970.
After the war, the area became predominantly African-American, as white residents were able to move freely to private housing elsewhere in Marin. Since the 1980s, additional development has changed the makeup of the population while providing more local jobs. The population in 2010 was 2,666. Marin City's socioeconomic and racial makeup contrasts with the mostly wealthy and Caucasian populations in Marin County.
