Hollister is a city in and the county seat of San Benito County, California. 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 when the San Justo Homestead Association purchased the property from William Welles Hollister (1818–1886). Undecided about a name for the new town, an association member, Napa vintner Henry Hagen, was tired of Saint and Spanish names in nearby towns and suggested the name Hollister.
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.
Hollister has a cool-summer mediterranean climate that has hotter summers than the Monterey–Salinas area but also being cooler than many other inland cities of the central part of the state. Although summers are cool due to the rapid fall of temperature after sunset, daytime temperatures between 70 °F (21 °C) and 80 °F (27 °C) or warmer are commonplace for more than half the year (April–October).
