The South Bay, also known as South County, is a region in southwestern San Diego County, California consisting of the cities and unincorporated communities of Bonita, Chula Vista, East Otay Mesa, Imperial Beach, Lincoln Acres, National City, and South San Diego.^[1]

Defined by its proximity to San Diego Bay and the Mexico-United States border, the South Bay is a mix of heavy industrial complexes and shipyards alongside beaches and residential developments. One of its cities, Imperial Beach, bills itself as "Classic Southern California" for being relatively untouched in terms of other coastal cities.^{[clarification needed]}
