Fremont is a city in Alameda County, California, United States. It was incorporated on January 23, 1956, from the annexation of Centerville, Niles, Irvington, Mission San José, and Warm Springs. The city is named after John C. Frémont, an American explorer and former US Senator and Military Governor of California.
Located in the southern end of the East Bay region of the San Francisco Bay Area, Fremont has a growing population of around 240,000. It is one of the largest cities by land area and the fourth most populous city in the San Francisco Bay Area, behind San Jose, San Francisco, and Oakland. It directly borders and is the closest East Bay city to Silicon Valley as formally defined, and is thus often associated with it. In the 2010s, the city’s technology sector experienced rapid growth.
The area consisting of Fremont and the cities of Newark and Union City is known collectively as the Tri-City Area; different from the adjacent Tri-Valley area encompassing Pleasanton, Dublin, and Livermore.
The recorded history of the Fremont area began on June 6, 1795, when Mission San José was founded by the Spaniard Father Fermin de Lasuen. The Mission was established at the site of the Ohlone village of Oroysom. On their second day in the area, the Mission party killed a grizzly bear in Niles Canyon.
