Vallejo (/vəˈleɪ(h)oʊ/ və-LAY-(h)oh; Spanish: [baˈʎexo]) is a waterfront city in Solano County, California, located in the North Bay subregion of the San Francisco Bay Area. Vallejo is geographically the closest North Bay city to the inner East Bay, so it is sometimes associated with that region. Its population was 115,942 at the 2010 census. It is the tenth most populous city in the San Francisco Bay Area, and the largest in Solano County. Vallejo sits on the northeastern shore of San Pablo Bay, 30 miles north of San Francisco, the northwestern shore of the Carquinez Strait and the southern end of the Napa River, 15 miles south of Napa. The city is named after General Mariano Guadalupe Vallejo, a native Californio, leading proponent of California’s statehood, and one of the first members of the California State Senate; the neighboring city of Benicia is named for his wife, Francisca Benicia Carrillo de Vallejo.
