Los Angeles County, officially the County of Los Angeles, is the most populous county in the United States, with more than 10 million inhabitants as of 2017. Its population is larger than that of 41 individual U.S. states. It is the third-largest metropolitan economy in the world, with a GDP of over $700 billion — larger than the GDPs of Belgium, Saudi Arabia, Norway and Taiwan. It has 88 incorporated cities and many unincorporated areas and at 4,083 square miles (10,570 km2), it is larger than the combined areas of the U.S. states of Delaware and Rhode Island. The county is home to more than one-quarter of California residents and is one of the most ethnically diverse counties in the U.S. Its county seat, Los Angeles, is also its most populous city at about four million.
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).

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 and Business Affairs – offers consumers in the county a variety of services including: consumer and real estate counseling, mediation, and small claims counseling investigates consumer complains, real estate fraud and identity theft issues. The department also provides small business certifications and helps entrepreneurs navigate the process of opening a business.
- Los Angeles County Department of Children and Family Services – administers foster care
- Los Angeles County Fire Department – provides firefighting services for the unincorporated parts of Los Angeles County, as well as 58 cities.
- 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 unincorporated parts of Los Angeles County, as well as 42 cities.

Los Angeles County has voted for the Democratic candidate in most of the presidential elections in the past four decades, and has gone Democratic in every election since 1988. However, 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 voted 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 2016, Democrat Hillary Clinton won 71% of the vote, marking the largest percentage of the electorate ever won by a single candidate in the county.
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 50.04% with a margin of 2,385 votes.
The Los Angeles Superior Court, is the county's court of general jurisdiction, while the U.S. District Court for the Central District of California may hear cases where federal jurisdiction is present. 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 International Airport (LAX), located in the Westchester district, is the primary commercial airport for commercial airlines in the county and the Greater Los Angeles Area. LAX is operated by Los Angeles World Airports (LAWA), an agency of the City of Los Angeles.
Other important commercial airports in Los Angeles County include:
- Long Beach Municipal Airport operated by the City of Long Beach.
- Bob Hope Airport in Burbank, operated by the Burbank-Glendale-Pasadena Airport Authority.
The following general aviation airports also are located in Los Angeles County:
- County operated airports (Department of Public Works, Aviation Division)
- City operated airports
- Van Nuys Airport in Van Nuys, also operated by LAWA. Van Nuys Airport sees significant executive jet air traffic.
- LA/Palmdale Regional Airport in Palmdale. The airport is a separate facility on the grounds of Air Force Plant 42.
- Santa Monica Airport in Santa Monica, which has major executive jet traffic.
- Hawthorne Municipal Airport, also known as Jack Northrop Field, in Hawthorne.
- Zamperini Field in Torrance.
The U.S. Air Force operates three airports in Los Angeles County:
- Portions of Edwards Air Force Base, located at the northern edge of the county.
- Air Force Plant 42 in Palmdale, sharing runways with LA/Palmdale Regional.
- The non-flying Los Angeles Air Force Base in El Segundo.
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 sea 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.
There are 88 incorporated cities in Los Angeles County. According to the 2016 Estimate, the most populous are:
