Kern County comprises the Bakersfield, California, Metropolitan statistical area. The county spans the southern end of the Central Valley. Covering 8,161.42 square miles (21,138.0 km2), it ranges west to the southern slope of the Coast Ranges, and east beyond the southern slope of the eastern Sierra Nevada into the Mojave Desert, at the city of Ridgecrest. Its northernmost city is Delano, and its southern reach expands just beyond Lebec to Grapevine, and the northern extremity of the parallel Antelope Valley.
The county's economy is heavily linked to agriculture and to petroleum extraction. There is also a strong aviation, space, and military presence, such as Edwards Air Force Base, the China Lake Naval Air Weapons Station, and the Mojave Air and Space Port.
The Battle of San Emigdio took place in Kern County in March 1824. The Chumash Indians of Mission Santa Barbara rebelled against the Mexican government taking over mission property and ejecting the natives. With Mexican forces from Monterey commanded by Carlos Carrillo, the battle occurred at the canyon where San Emigdio Creek flows down San Emigdio Mountain and the Blue Ridge, south of Bakersfield near today's Highway 166. It was a low-casualty encounter, with only four Indians killed and no Mexicans. The surviving Indians were pacified and brought back to Santa Barbara in June 1824 after a pursuit and negotiation in which many were allowed to keep their arms for the return march over the mountains.
In the beginning, the area that became Kern County was dominated by mining in the mountains and in the desert. In 1855 the California legislature attempted to form a county in the area by giving the southeastern territory of Tulare County on the west of the Sierra Nevada Mountains to Buena Vista County. However, it was never officially organized prior to 1859, when the enabling legislation expired. The south of Tulare County was later organized as Kern County in 1866, with additions from Los Angeles and San Bernardino Counties. Its first county seat was in the mining town of Havilah, in the mountains between Bakersfield and Tehachapi.
Settlers considered the flatlands inhospitable and impassable at the time due to swamps, lakes, tule reeds and diseases such as malaria. This changed when residents started draining lands for farming and constructing canals, most dug by hand by hired Chinese laborers. Within 10 years the valley surpassed the mining areas as the economic center of the county, and the county seat was moved as a result from Havilah to Bakersfield in 1874.
The county derives its name from the Kern River, which was named for Edward Kern, cartographer for General John C. Frémont's 1845 expedition, which crossed Walker Pass. The Kern River was originally named Rio Bravo de San Felipe by Father Francisco Garcés when he explored the area in 1776.
Severe earthquakes have struck Kern County within historical times, including the 1857 Fort Tejon earthquake.
On July 21, 1952, an earthquake occurred with the epicenter about 23 miles (37 km) south of Bakersfield. It measured 7.3 on the moment magnitude scale and killed 12 people. In addition to the deaths, it was responsible for hundreds of injuries and more than $60 million in property damage. The main shock was felt over much of California and as far away as Phoenix, Arizona and Reno, Nevada. The earthquake occurred on the White Wolf Fault and was the strongest to occur in California since the 1906 San Francisco earthquake. Tehachapi suffered the greatest damage and loss of life from the earthquake, though its effects were widely felt throughout central and southern California. The event had a significant aftershock sequence that persisted into July and August with the strongest coming on August 22, an M5.8 event with a maximum perceived intensity of VIII (Severe) and resulted in two additional deaths and an additional $10 million in property damage. Repercussions of the sequence of earthquakes were still being felt in the heavily damaged downtown area of Bakersfield well into the 1990s as city leaders attempted to improve safety of the surviving non-reinforced masonry buildings.
Following the event, a field survey was conducted along the fault zone with the goal of estimating the peak ground acceleration of the shock based on visually evaluating precarious rock formations and other indicators. Ground disturbances that were created by the earthquakes were also surveyed, both in the valley and in the foothills, with both vertical and horizontal displacements present in the epicenter area. The strong motion records that were acquired from the event were significant, and a reconnaissance report was recognized for its coverage of the event, and how it set a standard for those types of engineering or scientific papers.
Between 1983 and 1986, several ritual sex ring child abuse cases occurred in Kern County, resulting in numerous long prison sentences, all of which were overturned—some of them decades later, because the prosecutors had coerced false testimonies from the purported child victims. The details of these false accusations are covered extensively in the 2008 documentary Witch Hunt, narrated by Sean Penn.
According to the United States Census Bureau, the county has a total area of 8,163 square miles (21,140 km2), of which 8,132 square miles (21,060 km2) is land and 31 square miles (80 km2) (0.4%) is water. It is the third-largest county by area in California. Its area is nearly the size of the state of New Hampshire; it extends:
- East beyond the southern slope of the Sierra Nevada range into the Mojave Desert, and includes parts of the Indian Wells Valley and Antelope Valley.
- West from the Sierra across the floor of the San Joaquin Valley to the eastern edge of the Temblor Range, part of the Coast Ranges.
- South over the ridge of the Tehachapi Mountains.
Kern County suffers from severe air pollution. Particulates cause poor visibility, especially in the winter. Western Kern County lies in the San Joaquin Valley and the topography traps pollutants. Although the topography is not as unfavorable in eastern Kern County, eastern Kern County is a non-attainment area for particulates. Air pollution caused by particulates is "in the unhealthy range an average of 40 days a year, according to the American Lung Association's (ALA) 2018 State of the Air Report.
Chaparral comprises a considerable portion of the natural area within Kern County; the species diversity within these chaparral habitats, however, is considerably less than in many other regions of California. Whitethorn is a prominent example of chaparral species on the rocky slopes of the Sierra Nevada as well as the Inner Coastal Ranges. California Buckeye is a notable tree found in both chaparral and forests and whose southern range terminates in Kern County.
According to the 2010 United States Census, Kern County's population was 839,631. It was the eleventh-largest county by population in California. The center of population of California is located in Kern County, in the town of Buttonwillow .

Among those convicted were many charged with crimes against children during a moral panic. Many of these have since been released. Kern County contains multiple state and federal prisons, including two private prisons. As a result, the courts have been known to sentence a higher than average number of defendants to long prison sentences to help the local economy. The county is among the most prolific with the death penalty. assigning death penalty sentences in 26 cases since 1976. In 2015 Kern County policemen from all departments killed more people per capita than any other American county. Because of the very harsh local criminal justice system, Kern County has been dubbed "the most punitive authoritarian jurisdiction on the west coast" and "Oklahoma of the west" by major news websites such as Vice News. In 2015, it was revealed that the Kern County Sheriff's office engaged in a longstanding program of attempted cash payoffs to women who had accused deputies of sexual assault. Also in 2015, a civil lawsuit filed by a survivor of a sexual assault committed by Kern County Sheriff's deputy Gabriel Lopez, was settled for $1 million.
Kern County also holds the distinction of having the most deaths per capita in the US by police shooting per an article published in The Guardian on December 1, 2015.

Major producer of almonds with production greater than 100 million pounds annually.
As of 2015, Kern is California's top oil-producing county, with 78% of the state's 56,653 active oil wells and 71% of oil production. The county produced 144.5 million barrels of oil in 2015, accounting for about 4% of overall U.S. oil production.
Discovery and development
Oil development began with the 1894 discovery of the Midway-Sunset Oil Field, now the third-largest in the United States, in the southwestern portion of Kern County near Maricopa. The 1899 discovery along the Kern River was a breakthrough in oil production. Oil was refined here even before the establishment of the county. The Buena Vista Petroleum Company was organized and incorporated in 1864. Soon thereafter a refinery was built that operated until April 1867 when work ceased because of high freight charges.
Other big oil fields in southwestern Kern County discovered early in the 20th century include the Buena Vista, the South Belridge and the Cymric fields. The latter is the fastest-growing field in California in terms of barrels produced per year. Later large fields include the Kern River Oil Field, the fifth-largest in the U.S., the adjacent Kern Front Oil Field, the Mount Poso Oil Field in the lower foothills of the Sierra north-northeast of Bakersfield and the Fruitvale Oil Field, which underlies much of the city of Bakersfield, along and north of the Kern River.
On July 22, 2009, Occidental Petroleum announced it had discovered the equivalent of 150 million to 250 million barrels of oil in Kern County, which the company called the largest oil discovery in California in 35 years. The find added about 10 percent to California's known reserves. Occidental's Ray Irani said it is likely that more oil would be found in the areas outside the initial six wells that tapped the discovery. Occidental has not revealed the exact location of the find, two-thirds of which is natural gas. BNET, an industry web publication, said the find would add to the company's 708 million barrels of proven reserves in California.
