Sacramento County was incorporated in 1850 as one of the original 27 counties of the State of California. (Map of State) The County's largest city, the City of Sacramento, is the seat of government for the State of California and also serves as the county seat. Sacramento became the State Capital in 1854. The County is the major component of the Sacramento Metropolitan Statistical Area ("SMSA") which includes Sacramento, El Dorado, and Placer Counties.

Sacramento County encompasses approximately 994 square miles in the middle of the 400-mile long Central Valley, which is California's prime agricultural region. The County is bordered by Contra Costa and San Joaquin Counties on the south, Amador and El Dorado Counties on the east, Placer and Sutter Counties on the north, and Yolo and Solano Counties on the west. (Map of Bordering Counties) Sacramento County extends from the low delta lands between the Sacramento and San Joaquin rivers north to about ten miles beyond the State Capitol and east to the foothills of the Sierra Nevada Mountains. The southernmost portion of Sacramento County has direct access to the San Francisco Bay.
