Home to Silicon Valley, Santa Clara County is an economic center for high technology and has the third highest GDP per capita in the world (after Zurich, Switzerland and Oslo, Norway), according to the Brookings Institution. The county's concentration of wealth, primarily due to the tech industry, has made it the most affluent county on the West Coast of the United States and the most affluent outside the Washington metropolitan area and one of the most affluent places in the United States.
Santa Clara County is part of the San Jose-Sunnyvale-Santa Clara, CA Metropolitan Statistical Area as well as the San Jose-San Francisco-Oakland, CA Combined Statistical Area. Located on the southern coast of San Francisco Bay, the urbanized Santa Clara Valley within Santa Clara County is also known as Silicon Valley. Santa Clara is the most populous county in the San Francisco Bay Area and in Northern California.
Santa Clara County is named for Mission Santa Clara, which was established in 1777 and was in turn named for Saint Clare of Assisi.
Main article: History of Santa Clara County, California
Santa Clara County was one of the original counties of California, formed in 1850 at the time of statehood. The original inhabitants included the Ohlone, residing on Coyote Creek and Calaveras Creek. Part of the county's territory was given to Alameda County in 1853.
In 1882, Santa Clara County tried to levy taxes upon property of the Southern Pacific Railroad within county boundaries. The result was the U.S. Supreme Court case of Santa Clara County v. Southern Pacific Railroad, 118 U.S. 394 (1886), in which the Court extended Due Process rights to artificial legal entities.
In the early 20th Century, the area was promoted as the "Valley of the Heart's Delight" due to its natural beauty, including a significant number of orchards.
The first major technology company to be based in the area was Hewlett-Packard, founded in a garage in Palo Alto in 1939. IBM selected San Jose as its West Coast headquarters in 1943. Varian Associates, Fairchild Semiconductor, and other early innovators were located in the county by the late 1940s and 1950s. The U.S. Navy had a large presence in the area and began giving large contracts to Silicon Valley electronics companies. The term "Silicon Valley" was coined in 1971. The trend accelerated in the 1980s and 1990s, and agriculture has since then been nearly eliminated from the northern part of the county. Today, Santa Clara County is the headquarters for approximately 6500 high technology companies, including many of the largest tech companies in the world, among them hardware manufacturers AMD, Cisco Systems and Intel, computer and consumer electronics companies Apple Inc. and Hewlett-Packard, and internet companies eBay, Google, and Yahoo!. Most of what is considered to be Silicon Valley is located within the county, although some adjoining tech regions in San Mateo (e.g., Facebook), Alameda, and Santa Cruz counties are also considered part of Silicon Valley.
According to the U.S. Census Bureau, the county has a total area of 1,304 square miles (3,380 km2), of which 1,290 square miles (3,300 km2) is land and 14 square miles (36 km2) (1.1%) is water.
Counties which border with Santa Clara County are, clockwise, Alameda County, San Joaquin (within a few hundred feet at Mount Boardman), Stanislaus, Merced, San Benito, Santa Cruz, and San Mateo County. Santa Clara County formerly shared borders with Contra Costa, Mariposa, Monterey, and Tuolumne counties until 1853, 1874, and 1854 respectively (Monterey County currently comes within a few miles of Santa Clara).
The San Andreas Fault runs along the Santa Cruz Mountains in the south and west of the county.

In 1978, California Department of Fish and Game warden Henry Coletto urged the department to choose the Mount Hamilton area as one of California's relocation sites under a new statewide effort to restore tule elk (Cervus canadensis ssp. nannodes). While other ranchers refused, tech pioneers Bill Hewlett and David Packard allowed Coletto and state biologists to translocate the initial 32 tule elk from the Owens Valley in the eastern Sierra onto the 28,000-acre (11,000 ha) San Felipe Ranch, which the families jointly own, in the hills east of Morgan Hill. From the three original 1978–1981 translocations (totaling 65 animals) to the Mount Hamilton region of the Diablo Range, there are multiple herds in different locations including the Isabel Valley, San Antonio Valley, Livermore area, San Felipe Ranch, Metcalf Canyon, Coyote Ridge, Anderson Lake, and surrounding areas such as the Sunol and Cottonwood Creek (near San Luis Reservoir) herds. As of 2012, an estimated 400 tule elk roam 1,875 square kilometres (724 sq mi) in northeastern Santa Clara County and southeastern Alameda County. In March 2014 CDFW translocated nine bull elk from the San Luis National Wildlife Refuge to add genetic diversity to the San Antonio Valley Ecological Reserve herd in San Antonio Valley in extreme eastern Santa Clara County. As of 2017 there were four herds in the Coyote Ridge area, often visible from U. S. Highway 101, according to Craige Edgerton, recently retired executive director of the Silicon Valley Land Conservancy and local naturalist Michael Hundt. In 2019, a fifth herd of tule elk was documented by local naturalist Roger Castillo, likely having split from the Coyote Ridge herd and established itself in Silver Creek Valley around the closed Ranch Golf Club.
Pronghorn (Antilocapra americana) were historically native to Santa Clara County. In June 1776, Lieutenant Commander Don Jose Joaquin Morago led a group of soldiers and colonists from the Presidio of Monterey to establish Mission San Francisco de Asis and found pronghorn: “In the said plains of San Bernardino [Santa Clara Valley]…there is another species of deer about the size of three-year-old sheep. They are similar in appearance to the deer, except that they have short horns and also short legs like the sheep. They live in the plains where they go in herds of 100, 200, or more. They run all together over the plains so fast that they seem to fly…These animals are called berrendos and there are many of them also in the southern Missions wherever the country is level.” In 1990, the California Department of Fish and Game's Henry Coletto translocated excess pronghorn from Modoc County to six locations in California, including 51 animals to the San Felipe Ranch in Santa Clara County, where the swift-footed ungulates had not lived for generations. The animals left the San Felipe Ranch for the Isabel and San Antonio Valleys, as well as an area near Lake Del Valle in Alameda County may now be extirpated by poaching, highway vehicle collisions, and insufficient numbers to defend pronghorn fawns against coyote predation. As of 2012, the Isabel Valley Ranch herd had dwindled to 3 animals, and the Lake del Valle herd to 13. Currently, iNaturalist.org has zero observer records of pronghorn in Santa Clara County.
The Nature Conservancy "Mount Hamilton Project" has acquired or put under conservation easement 100,000 acres (40,000 ha) of land towards its 500,000 acres (200,000 ha) goal for habitat conservation within a 1,200,000 acres (490,000 ha) area encompassing much of eastern Santa Clara County as well as portions of southern Alameda County, western Merced and Stanislaus Counties, and northern San Benito County. Acquisitions to date include the 1,756-acre (711 ha) Rancho Ca?ada de Pala, straddling the Alameda Creek and Coyote Creek watersheds for California tiger salamander habitat; a conservation easement on the 3,259-acre Blue Oak Ranch Reserve, which abuts the north side of Joseph D. Grant County Park; a conservation easement on the 28,359-acre San Felipe Ranch, connecting Joseph D. Grant County Park with Henry W. Coe State Park; the 2,899-acre South Valley Ranch which protects a tule elk herd in the San Antonio Valley, and other properties.
As of 1980, Santa Clara County has the highest number of Superfund Sites of any county in the United States, accounting for 25 polluted locations requiring a long-term response to clean up hazardous material contaminations. The vast majority of these Superfund sites were caused by firms associated with the high tech sector located in Silicon Valley.
Census demographics data released in 2019 shows that Asian-Americans have had the plurality of Santa Clara's population since 2014.

The San Jose/Sunnyvale/Santa Clara metropolitan region, comprising Santa Clara County and San Benito County, was ranked as the highest performing metropolitan area in the US in 2012, ahead of Austin, Texas and Raleigh, North Carolina, according to the Milken Institute. The GDP of the metro area reached $176.7 billion in 2011, or $94,587 per capita, roughly on par with Qatar in both total GDP and per capita (nominal). GDP grew a strong 7.7% in 2011, and in contrast with most of California, GDP and per capita GDP (nominal) is well above 2007 (financial crisis) levels. Despite relative wealth vis a vis other regions nationally, a large underclass exists whose income is roughly equivalent to that elsewhere in the country, despite extreme land prices. The surge in metro GDP is highly correlated with home prices, which for average single-family homes passed $1 million ($1,017,528) in August 2013.

Freeways and expressways
The county has an extensive freeway system and a separate expressway system (though it's not as extensive as those in Southern California). Expressways in California are distinct from freeways; although access to adjoining properties is eliminated, at-grade intersections are allowed. However, unlike expressways virtually everywhere else in California, the Santa Clara County expressways were built, signed, and maintained as county roads; they are not maintained by Caltrans, although they are patrolled by the California Highway Patrol.
There is also a large street network dominated by four- and six-lane arterials. Some of the newer boulevards (primarily in the West Valley) are divided with landscaped medians.
