The South Bay is a region of the southwest peninsula of Los Angeles County, California. The name stems from its geographic feature of the Palos Verdes peninsula extended westward, creating a bay at the southern area of the Santa Monica Bay of the Pacific Ocean.
The broadest definition of the South Bay includes all the communities south of Interstate 105 and west of Long Beach (with the exception of Compton, which is considered South Los Angeles). The South Bay includes the beach cities of Manhattan Beach, Hermosa Beach and Redondo Beach), El Segundo, the Palos Verdes Peninsula (which comprises the cities of Rancho Palos Verdes, Rolling Hills, Rolling Hills Estates, and Palos Verdes Estates), Inglewood, Hawthorne, Gardena, Carson, Lawndale, Harbor City, Torrance, Lomita, and San Pedro. The region is bordered on the north by the Westside, on the northeast by South Los Angeles, on the east by the Gateway cities, and on the south and west by the Pacific Ocean.
