Riverside County is included in the Riverside–[[San Bernardino, California|San Bernardino]]–[[Ontario, California|Ontario]] [[Metropolitan Statistical Area]], also known as the [[Inland Empire]] included in the [[Greater Los Angeles Area]].

Roughly rectangular, Riverside County covers {{convert|7208|sqmi|km2}} in [[Southern California]], spanning from the greater Los Angeles area to the [[Arizona]] border. Geographically, the western region of the county is [[chaparral]] with a [[Mediterranean climate]], while the central and eastern regions of the county are predominantly [[desert]] or mountainous. Most of [[Joshua Tree National Park]] is located in the county. The desert [[resort cities]] of [[Indio, California|Indio]], [[Coachella, California|Coachella]], [[Palm Springs]], [[Palm Desert]], [[Indian Wells, California|Indian Wells]], [[La Quinta, California|La Quinta]], [[Rancho Mirage, California|Rancho Mirage]], [[Cathedral City, California|Cathedral City]] and [[Desert Hot Springs]] are located in the [[Coachella Valley]] region of central-eastern Riverside County.

Between 2007 and 2011, large numbers of [[Los Angeles metropolitan area|Los Angeles]]-area workers moved to the county to take advantage of more affordable housing.<ref>{{cite web|url=http://la.curbed.com/2014/2/6/10146308/why-are-people-fleeing-los-angeles-for-san-bernardino|title=Why Are People Fleeing Los Angeles For San Bernardino?|first=Bianca|last=Barragan|date=February 6, 2014|website=La.curbed.com|access-date=May 20, 2016|archive-date=May 7, 2016|archive-url=https://web.archive.org/web/20160507162846/http://la.curbed.com/2014/2/6/10146308/why-are-people-fleeing-los-angeles-for-san-bernardino|url-status=dead}}</ref> Along with neighboring San Bernardino County, it was one of the fastest-growing regions in the state prior to the recent changes in the regional economy.

==Location== Riverside County is bordered on the north by [[San Bernardino County, California|San Bernardino County]]; on the east by [[La Paz County, Arizona|La Paz County]], [[Arizona]]; on the southeast by [[Imperial County, California|Imperial County]]; on the southwest by [[San Diego County, California|San Diego County]]; and on the west by [[Orange County, California|Orange County]].

==Etymology== {{Main|List of Riverside County, California, placename etymologies}} When Riverside County was formed in 1893, it was named for the city of Riverside, the county seat. That city, founded in 1870, was so named because of its location near the [[Santa Ana River]].<ref>Capace, Nancy (1999). ''Encyclopedia of California''. North American Book Dist LLC.

==History==

===Indigenous=== [[File:Cahuilla kumeyaay map.svg|left|thumb|200x200px|The homelands of the [[Cahuilla]] include a large area of Riverside County.]] The [[Indigenous peoples of California|Indigenous peoples]] of the valleys, mountains and deserts of what is now Riverside County are the [[Serrano people|Serrano]], the [[Payómkawichum]], the [[Mohave people|Mohave]], the [[Cupeño|Cupeno]], the [[Chemehuevi]], the [[Cahuilla]], and the [[Tongva]].<ref>{{Cite book |last=Trafzer |first=Clifford E. |title=Native Americans of Riverside County |date=2006 |publisher=Arcadia Pub |others=Jeffrey A.

The inland valleys in the [[Santa Rosa Mountains (California)|Santa Rosa]] and [[San Jacinto Mountains]] and the desert of the [[Salton Sink]] are the traditional homelands of the Cahuilla.

===Spanish era=== The first European settlement in the county was a [[Mission San Luis Rey de Francia]] estancia or farm at the Luiseño village of Temescal. In 1819, the Mission granted [[Leandro Serrano]] permission to occupy the land for the purpose of grazing and farming, and Serrano established [[Rancho Temescal (Serrano)|Rancho Temescal]]. Serrano was [[majordomo|mayordomo]] of [[San Antonio de Pala Asistencia]] for the Mission of San Luis Rey.

===Mexican era=== With the signing of the [[Treaty of Cordoba]] in 1821, Mexico gained its independence from [[Spain]], but the [[Mission San Gabriel Arcángel|San Gabriel Mission]] near what is now [[Los Angeles, California]], continued to expand, and established [[Rancho San Gorgonio (San Gabriel Mission)|Rancho San Gorgonio]] in 1824. The ranch was to be one of the Mission's principal ''rancherias'', and the most distant, and it occupied most of today's [[San Gorgonio Pass]] area.<ref>{{cite book |last1=Gunther |first1=Jane Davies |title=Riverside County, California, Place Names; Their Origins and Their Stories |date=1984 |location=Riverside, California |pages=456–461}}</ref><ref>{{cite book |last1=Gudde |first1=Erwin G. |title=California Place Names |date=1949 |publisher=University of California Press |location=Berkeley and Los Angeles |page=305 |edition=1st}}</ref>

Following the [[Mexican secularization act of 1833]] by the [[First Mexican Republic]], a series of rancho land grants were made throughout the state. In the Riverside County this included; [[Rancho Jurupa]] in 1838, [[Rancho El Rincon (Bandini)|El Rincon]] in 1839, [[Rancho San Jacinto Viejo]] in 1842, [[Rancho San Jacinto y San Gorgonio]] in 1843, Ranchos [[Rancho La Laguna (Manriquez)|La Laguna]], [[Rancho Pauba|Pauba]], [[Rancho Temecula|Temecula]] in 1844, Ranchos [[Rancho Little Temecula|Little Temecula]], [[Rancho Potreros de San Juan Capistrano|Potreros de San Juan Capistrano]] in 1845, Ranchos [[Rancho San Jacinto Sobrante|San Jacinto Sobrante]], [[Rancho La Sierra (Sepulveda)|La Sierra (Sepulveda)]], [[Rancho La Sierra (Yorba)|La Sierra (Yorba)]], [[Rancho Santa Rosa (Moreno)|Santa Rosa]] and [[Rancho San Jacinto Nuevo y Potrero|San Jacinto Nuevo y Potrero]] in 1846.

[[New Mexico|New Mexican]] colonists founded the town of [[La Placita, California|La Placita]] on the east side of the [[Santa Ana River]] at the northern extremity of what is now the city of [[Riverside, California|Riverside]] in 1843.

===American era=== When the initial 27 California counties were established in 1850, the area today known as Riverside County was divided between [[Los Angeles County]] and [[San Diego County]]. In 1853, the eastern part of Los Angeles County was used to create [[San Bernardino County]]. Between 1891 and 1893, several proposals and legislative attempts were put forth to form new counties in [[Southern California]]. These proposals included one for a Pomona County and one for a San Jacinto County. None of the proposals were adopted until a measure to create Riverside County was signed by Governor [[Henry Markham|Henry H. Markham]] on March 11, 1893.<ref name=fitch1>Fitch, pages v–viii.</ref>

====County formation==== The new county was created from parts of [[San Bernardino County, California|San Bernardino County]] and [[San Diego County, California|San Diego County]]. On May 2, 1893, seventy percent of voters approved the formation of Riverside County. Voters chose the city of Riverside as the county seat, also by a large margin. Riverside County was officially formed on May 9, 1893, when the Board of Commissioners filed the final canvass of the votes.<ref name=fitch1/>

Riverside county was a major focal point of the [[Civil Rights Movement]]s in the US, especially the African-American sections of Riverside and heavily Mexican-American communities of the Coachella Valley visited by [[Cesar Chavez]] of the farm labor union struggle.

Riverside county has also been a focus of modern [[Indigenous peoples of the Americas|Native American]] [[Native American gaming|Gaming]] enterprises. In the early 1980s, the county government attempted to shut down small bingo halls operated by the [[Morongo Band of Cahuilla Mission Indians]] and the [[Cabazon Band of Mission Indians]]. The tribes joined forces and fought the county all the way to the U.S. Supreme Court, which ruled in the tribes' favor on February 25, 1987.<ref>''California v. Cabazon Band'', {{ussc|480|202|1987}}.</ref> In turn, Congress enacted the [[Indian Gaming Regulatory Act]] in 1988 to establish a legal framework for the relationship between Indian gaming and state governments. Naturally, both tribes now operate large casinos in the county: the [[Morongo Casino, Resort & Spa]] and the [[Fantasy Springs Resort Casino]] adjacent to [[Spotlight 29 Casino]].

==Geography== [[File:El Paseo (Palm Desert) 04.jpg|thumb|right|220px|El Paseo in [[Palm Desert|Palm Desert, California]]]] According to the [[U.S. Census Bureau]], the county has a total area of {{convert|7303|sqmi}}, of which {{convert|7206|sqmi}} is land and {{convert|97|sqmi}} (1.3%) is water.<ref name="GR1">{{cite web|url=http://www2.census.gov/geo/docs/maps-data/data/gazetteer/counties_list_06.txt|publisher=United States Census Bureau|access-date=October 3, 2015|date=August 22, 2012|title=2010 Census Gazetteer Files}}</ref> It is the fourth-largest county in California by area. At roughly {{convert|180|mi|km|0}} wide in the east–west dimension, the area of the county is massive. Riverside County, California is roughly the size of the State of New Jersey in total area. County government documents frequently cite the [[Colorado River]] town of [[Blythe, California|Blythe]] as being a "three-hour drive" from the county seat, [[Riverside, California|Riverside]]. Some view the areas west of San Gorgonio Pass as the Inland Empire portion of the county and the eastern part as either the [[Mojave Desert]] or [[Colorado Desert]] portion. There are probably at least three geomorphic provinces: the [[Inland Empire]] western portion, the [[Santa Rosa Mountains (California)|Santa Rosa Mountains]] communities such as [[Reinhardt Canyon]], and the desert region. Other possible subdivisions include tribal lands, the Colorado River communities, and the [[Salton Sea]].

There is a diversity of flora and fauna within Riverside County. Vegetative plant associations feature many desert flora, but there are also forested areas within the county. The California endemic [[Blue oak]], ''[[Quercus douglasii]]'' is at the southernmost part of its range in Riverside County.<ref>C.

==Government and law enforcement== ===Government=== [[File:Riverside County Courthouse, 1903.jpg|thumb|220px|[[Riverside County Historic Courthouse]]]]

The Government of Riverside County operates as a [[Charter county|general law county]] under the [[California Constitution]] and [[California law|law]]. It does not have a county charter.<ref>{{cite web|url=https://www.counties.org/counties/county-structure/|title=County Structure|website=California State Association of Counties |access-date=April 19, 2026|archive-url=https://web.archive.org/web/20260318093837/https://www.counties.org/counties/county-structure/ |archive-date=March 18, 2026 |url-status=live}}</ref> 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.

The county is governed by a five-member Board of Supervisors, with each member elected by districts for four-year terms.<ref>Fitch, page 1.</ref> In 1999, the Board of Supervisors approved a multimillion-dollar planning effort to create the Riverside County Integrated Plan (RCIP) which was to encompass a completely new General Plan, regional transportation plan (CETAP) and Habitat Conservation Plan. The resultant General Plan adopted in 2003 was considered groundbreaking for its multidisciplinary approach to land use and conservation planning.<ref>Riverside County RCIP General Plan (2003), The Planning Center</ref><ref>Riverside County Integrated Project: An innovative model for integrating land use, transportation and conservation planning (2007), Edward J.

Bush]] in [[2004 United States presidential election in California|2004]]. At the state level, Riverside remains one of the most conservative counties in Southern California and is frequently the only county in the region to not vote for Democratic candidates, having not voted for a Democrat for governor since 1998 (and having only voted three times for Democrats in the past century).

At the local level, Democrats are strongest in Riverside County in large cities such as Riverside, Perris, and Moreno Valley, performing especially well in majority Black and Hispanic areas, although those have been shifting heavily to the right. Democrats are also strongest in progressive-leaning White areas and college campuses such as Downtown Riverside, the area surrounding [[University of California, Riverside|UC Riverside]], the LGBT enclave of [[Palm Springs, California|Palm Springs]] and most of the Hispanic-majority [[Coachella Valley]].<ref name=":0">{{Cite news |last1=Datar |first1=Saurabh |last2=Marcus |first2=Ilana |last3=Murray |first3=Eli |last4=Singer |first4=Ethan |last5=Lemonides |first5=Alex |last6=Zhang |first6=Christine |date=2025-01-15 |title=An Extremely Detailed Map of the 2024 Election |url=https://www.nytimes.com/interactive/2025/us/elections/2024-election-map-precinct-results.html |access-date=2025-04-04 |work=The New York Times |language=en-US |issn=0362-4331}}</ref>

Republicans perform especially well in the wealthy San Diegan exurbs in the [[Temecula Valley]] as well as more middle-class white cities such as [[Lake Elsinore, California|Lake Elsinore]], [[Wildomar, California|Wildomar]], and [[Menifee, California|Menifee]]. Republicans are also usually more successful in the rural areas of the county as well as wealthy retirement enclaves such as [[Canyon Lake, California|Canyon Lake]] and [[Bermuda Dunes, California|Bermuda Dunes]].<ref name=":0" /> Republicans have been consistently gaining in almost all areas of the county, however, and in 2024 put up massive gains in both affluent suburbs and blue-collar majority Hispanic areas, even flipping the city of [[Jurupa Valley, California|Jurupa Valley]], the most Hispanic city in Riverside County.<ref>{{Cite web |date=2025-01-05 |title=Here's how Donald Trump won the Inland Empire, city by city |url=https://www.dailybulletin.com/2025/01/05/heres-how-donald-trump-won-the-inland-empire-city-by-city/ |access-date=2025-04-04 |website=Daily Bulletin |language=en-US|author-last1=Horseman|author-first1=Jeff}}</ref>
