San Joaquin County (pron.: / /) is a county located in Central Valley of the U.S. state of California, just east of the San Francisco Bay Area. As of the 2010 census, the population was 685,306. The county seat is Stockton.
San Joaquin County was one of the original counties of California, created in 1850 at the time of statehood.
The county takes its name from the San Joaquin River. In the early 19th century Lieutenant Gabriel Moraga, commanding an expedition in the lower great California Central Valley, gave the name of San Joaquin (meaning Joachim) to the San Joaquin River that springs from the southern Sierra Nevada. San Joaquin County is also home to the site of the San Joaquin Valley's first permanent residence.
Between 1843 and 1846, during the era when California was a province of independent Mexico, five Mexican land grants were made in what became San Joaquin County: Campo de los Franceses, Pescadero (Grimes), Pescadero (Pico), Sanjon de los Moquelumnes and Thompson.
From 2007–present, the TV Show Sons of Anarchy takes place in San Joaquin County.
Tracy tire fire 
On August 7, 1998, a tire fire ignited at S.F. Royster's Tire Disposal just south of Tracy on South MacArthur Drive, near Linne Rd. The tire dump held over 7 million illegally stored tires and was allowed to burn for over two years before it was extinguished. Allowing the fire to burn was considered to be a better way to avoid groundwater contamination than putting it out. The cleanup cost $16.2 million and wound up contaminating local groundwater anyway.
San Joaquin County is centered near Stockton at about 37°54'N 121°12'W (37.9,-121.2).

Government and politics 
The Government of San Joaquin County is defined and authorized under the California Constitution and California law as a general law county. Much of the Government of California is in practice the responsibility of county governments, such as the Government of San Joaquin County. The County government provides countywide services such as elections and voter registration, law enforcement, jails, vital records, property records, tax collection, public health, and social services. In addition the County serves as the local government for all unincorporated areas. Some chartered cities such as Stockton and Tracy provide their own municipal services such as police, public safety, libraries, parks and recreation, and zoning. Some other cities arrange to have the County provide some or all of these services on a contract basis.
The County government is composed of the elected five-member Board of Supervisors (BOS), which operates in a legislative, executive, and quasi-judicial capacity; several other elected offices including the Sheriff, District Attorney, and Assessor; and numerous county departments and entities under the supervision of the County Administrator. As of December 2012 its members are:
- Carlos Villapudua, District 1
- Frank L. Ruhstaller, District 2
- Steve J Bestolarides, District 3, Chairman
- Ken Vogel, District 4, Vice-Chairman
- Leroy Ornellas, District 5
In addition, several entities of the government of California have jurisdiction conterminous with San Joaquin County, such as the San Joaquin County Superior Court, and the California Department of Corrections and Rehabilitation operates the Deuel Vocational Institution a state prison in unincorporated San Joaquin County near Tracy.
