San Francisco Bay Area is a Region in California at latitude 37° 37′ 48″ North, longitude 122° 25′ 26″ West.

The San Francisco Bay Area is a geographically large mix of urban, suburban and rural areas usually comprised of nine counties of California: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. The United States Census Bureau defines a "Combined Statistical Area" (CSA) of these nine counties, plus two more, (Santa Cruz and San Benito), for a total of eleven counties designated the "San Jose-San Francisco-Oakland, CA CSA." This larger CSA contains 7.46 million people—the sixth-largest CSA in the United States.

There are separate wiki pages for Alameda County, California, Marin County, California, Napa County, California, San Mateo County, Santa Cruz County, California, and South Bay (SF), California, the latter of which comprises most of Santa Clara county, sometimes roughly coterminous with Silicon Valley. San Francisco, California has its own separate wiki page, too, and is both a city and county each coterminous with each other.
