Los Angeles County is one of the original counties of California, created at the time of statehood in 1850. The county originally included parts of what are now Kern, San Bernardino, Riverside and Orange counties. As the population increased, sections were split off to organize San Bernardino County in 1853, Kern County in 1866, and Orange County in 1889.
According to the U.S. Census Bureau, the county has an area of 4,751 square miles (12,310 km2), of which 4,058 square miles (10,510 km2) is land and 693 square miles (1,790 km2) (15%) is water. Los Angeles County borders 70 miles (110 km) of coast on the Pacific Ocean and encompasses mountain ranges, valleys, forests, islands, lakes, rivers, and desert. The Los Angeles River, Rio Hondo, the San Gabriel River and the Santa Clara River flow in Los Angeles County, while the primary mountain ranges are the Santa Monica Mountains and the San Gabriel Mountains. The western extent of the Mojave Desert begins in the Antelope Valley, in the northeastern part of the county. Most of the population of Los Angeles County is located in the south and southwest, with major population centers in the Los Angeles Basin, San Fernando Valley and San Gabriel Valley. Other population centers are found in the Santa Clarita Valley, Pomona Valley, Crescenta Valley and Antelope Valley.
The county is divided west-to-east by the San Gabriel Mountains, which are part of the Transverse Ranges of southern California, and are contained mostly within the Angeles National Forest. Most of the county's highest peaks are in the San Gabriel Mountains, including Mount San Antonio 10,068 feet (3,069 m)) at the Los Angeles-San Bernardino county lines, Mount Baden-Powell 9,399 feet (2,865 m), Mount Burnham 8,997 feet (2,742 m) and Mount Wilson 5,710 feet (1,740 m). Several lower mountains are in the northern, western, and southwestern parts of the county, including the San Emigdio Mountains, the southernmost part of Tehachapi Mountains and the Sierra Pelona Mountains.

Law, government and politics
The Government of Los Angeles County is defined and authorized under the California Constitution, California law and the Charter of the County of Los Angeles. Much of the Government of California is in practice the responsibility of local governments such as the Government of Los Angeles County.
The county's voters elect a governing five-member Los Angeles County Board of Supervisors. The small size of the board means each supervisor represents over 2 million people. The board operates in a legislative, executive, and quasi-judicial capacity. As a legislative authority, it can pass ordinances for the unincorporated areas (ordinances that affect the whole county, like posting of restaurant ratings, must be ratified by the individual city). As an executive body, it can tell the county departments what to do, and how to do it. As a quasi-judicial body, the Board is the final venue of appeal in the local planning process, and holds public hearings on various agenda items.
As of 2008, the Board of Supervisors oversees a $22.5 billion annual budget and approximately 100,000 employees. The county government is managed on a day-to-day basis by a Chief Executive Officer and is organized into many departments, each of which is enormous in comparison to equivalent county-level (and even many state-level) departments anywhere else in the United States. Some of the larger or better-known departments include:
- Los Angeles County Department of Consumer Affairs – offers consumers in the county a variety of services including: consumer and real estate counseling, mediation, and small claims counseling. The department also investigates: consumer complains, real estate fraud and identity theft issues.
- Los Angeles County Department of Children and Family Services – administers foster care
- Los Angeles County Fire Department – provides fire protection, suppression, and prevention as well as emergency medical services
- Los Angeles County Department of Health Services – operates several county hospitals and a network of primary care clinics,
- Los Angeles County Department of Public Health - administers public health programs including STD programs, smoking cessation, and restaurant inspection. In the majority of the county LACDPH puts letter grades relating to the food cleanliness and safety of a restaurant in the front window of restaurants.
- Los Angeles County Department of Public Social Services – administers many federal and state welfare programs
- Los Angeles County Department of Public Works – operates countywide flood control system, constructs and maintains roads in unincorporated areas
- Los Angeles County District Attorney – prosecutes criminal suspects.
- Los Angeles County Office of the Public Defender – Defends indigent people accused of criminal offenses.
- Los Angeles County Probation Department
- Los Angeles County Sheriff's Department – provides law enforcement services for the entire County of Los Angeles, which includes the unincorporated areas, contract cities, and incorporated cities with municipal police forces. It is also responsible for operating the county jails and executing court orders and judicial security. The LASD is the largest county Sheriff's Department in the United States.
The Los Angeles County Metropolitan Transportation Authority, despite its name, is not a County department. Technically it is a state-mandated county transportation commission that also operates bus and rail.

Los Angeles County has voted for the Democratic candidate in most of the presidential elections in the past four decades, although it did vote twice for Dwight Eisenhower (1952, 1956), Richard Nixon (1968, 1972), and Ronald Reagan (1980, 1984) the latter two of whom were Californians. From 1920 to 1984 it was a bellwether county that always voted for the eventual national winner. It then has gone against the national popular vote winner in 1988 and 2004. In 2008 and 2012 approximately 69% of the electorate voted for Democrat Barack Obama.
In the United States House of Representatives, Los Angeles County is split between 18 congressional districts: In the California State Senate, Los Angeles County is split between 15 legislative districts: In the California State Assembly, Los Angeles County is split between 24 legislative districts:
On November 4, 2008, Los Angeles County was almost evenly split over Proposition 8 which amended the California Constitution to ban same-sex marriages. The county voted for the amendment 50.1% with a margin of 2,385 votes.
The Los Angeles Superior Court, has jurisdiction over all cases arising under state law, while the U.S. District Court for the Central District of California hears all federal cases. Both are headquartered in a large cluster of government buildings in the city's Civic Center.
Historically, the courthouses were county-owned buildings that were maintained at county expense, which created significant friction since the trial court judges, as officials of the state government, had to lobby the county Board of Supervisors for facility renovations and upgrades. In turn, the state judiciary successfully persuaded the state Legislature to authorize the transfer of all courthouses to the state government in 2008 and 2009 (so that judges would have direct control over their own courthouses). Courthouse security is still provided by the county government under a contract with the state.
Unlike the largest city in the United States, New York City, all of the city of Los Angeles and most of its important suburbs are located within a single county. As a result, both the county superior court and the federal district court are respectively the busiest courts of their type in the nation.
Many celebrities like O. J. Simpson have been seen in Los Angeles courts. In 2003, the television show Extra (based in nearby Glendale) found itself running so many reports on the legal problems of local celebrities that it spun them off into a separate show, Celebrity Justice.
State cases are appealed to the Court of Appeal for the Second Appellate District, which is also headquartered in the Civic Center, and then to the California Supreme Court, which is headquartered in San Francisco but also hears argument in Los Angeles (again, in the Civic Center). Federal cases are appealed to the Court of Appeals for the Ninth Circuit, which hears them at its branch building in Pasadena. The court of last resort for federal cases is the U.S. Supreme Court in Washington, D.C.

Los Angeles is a major freight railroad transportation center, largely due to the large volumes of freight moving in and out of the county's port facilities. The ports are connected to the downtown rail yards and to the main lines of Union Pacific and Burlington Northern Santa Fe headed east via a grade-separated, freight rail corridor known as the Alameda Corridor.
Amtrak has the following intercity Amtrak service at Union Station in the city of Los Angeles.
- The Pacific Surfliner to Santa Barbara, San Luis Obispo, and San Diego.
- The Coast Starlight to Seattle
- The Southwest Chief to Chicago
- The Sunset Limited to New Orleans and Orlando
Union Station is also the primary hub for Metrolink commuter rail, which serves much of the Greater Los Angeles Area.
Light rail, subway (heavy rail), and long-distance bus service are all provided by the Los Angeles County Metropolitan Transportation Authority (Metro).
The county's two main seaports are the Port of Los Angeles and the Port of Long Beach. Together they handle over a quarter of all container traffic entering the United States, making the complex the largest and most important port in the country, and the third-largest port in the world by shipping volume.
The Port of Los Angeles is the largest cruise ship center on the West Coast, handling more than 1 million passengers annually.
The Port of Long Beach is home to the Sea Launch program, which uses a floating launch platform to insert payloads into orbits that would be difficult to attain from existing land-based launch sites.
