Hollister is a city in and the county seat of San Benito County, California, United States. The population was 34,928 at the 2010 census. Hollister is primarily an agricultural town.
The Mutsun Ohlone Indians were the first known inhabitants of the Hollister region.
The town, then located in Monterey County, was founded November 19, 1868 originally as the San Justo Homestead Association, established by William Welles Hollister (1818–1886), a group that originally intended to name it San Justo. An association member, Napa vintner Henry Hagen, objected. Hagen argued that place names in California were dominated by Spanish saint names, and suggested that the state should have a town named after someone less holy. The City was incorporated on August 29, 1872. The western portion of San Benito County, including Hollister, was separated from Monterey County in 1874. The county was expanded eastward in 1887 to include portions taken from Merced and Fresno Counties.
