Santa Clara County is a county located in the San Francisco Bay Area of California. It contains major cities such as San Jose, Palo Alto, Mountain View, and Sunnyvale, and is a core of Silicon Valley. The county is notable for its concentration of technology firms, research institutions, and cultural landmarks including Stanford University, NASA Ames Research Center, and the Winchester Mystery House.
The area was originally inhabited by the Ohlone people and later colonized during the Spanish colonization of the Americas with establishments like Mission Santa Clara de Asís. Following Mexican independence and the Mexican–American War, land grants such as the Rancho San Antonio (Peralta) and Rancho Rinconada de Los Gatos shaped settlement patterns. The county experienced rapid growth during the California Gold Rush era and later with the rise of Stanford University in the late 19th century. In the 20th century, military and aerospace projects at Moffett Federal Airfield and NASA Ames Research Center and companies like Hewlett-Packard and Fairchild Semiconductor catalyzed the transformation into Silicon Valley. Recent decades have seen expansion by corporations including Apple Inc., Google, Facebook, Intel, and Cisco Systems.
The county spans portions of the Santa Cruz Mountains, the Valley of Santa Clara, and the southern shoreline of the San Francisco Bay.
