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 southeast San Francisco Bay Area and straddling both the East Bay and South Bay regions, Fremont has a rapidly-growing population of around 230,000. 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. The city has an extensive and rapidly expanding base of both tech industry and workers. 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.
