This article is about the region in northern California. For the region in Los Angeles County, see South Bay (Los Angeles County)

The South Bay is the region of the Bay Area around and south of the San Francisco Bay. No legal or geographic border precisely defines the point at which you leave the Peninsula and enter the South Bay, but it's safe to say that the Peninsula comprises Palo Alto and points north, while Mountain View and points south are in the South Bay. Similarly, as you travel south in the East Bay, you enter the South Bay upon entering Milpitas.

The South Bay includes part of the Silicon Valley, where many famous technology companies are located.

• San Benito County - South of Santa Clara County, San Benito County is an inland county dominated by the Coast Mountain Range. It is relatively sparsely populated, with only about 55,000 inhabitants. Pinnacles National Park and its dramatic rock formations lies in this county, as well as the town of San Juan Bautista and its historic mission.
• Monterey County - Southwest of Santa Clara County, Monterey County is what many people think of when they think of the Central Coast - the Monterey Bay Aquarium, the beautiful 17-Mile Drive, Cannery Row, Pebble Beach golf course, and the rugged beauty of Big Sur. The northern part of the county contains every manner of amenity for travelers, ranging from chain motels to five star resorts, while the southern portion of the county is remote and accessible mainly by the Pacific Coast Highway or on foot by hikers.
• Santa Cruz County - Located west of Santa Clara County, the second-smallest county in the state is home to the quirky town of Santa Cruz and a rugged coast that is equally popular with surfers and elephant seals. The Santa Cruz Mountains are the abode of redwoods and bright yellow banana slugs, both of which can be easily seen on the many hiking trails. Other portions of the county are known for agriculture, with farm stands dotting the roads.
