San Benito County was formed from parts of Monterey County in 1874.
The county is named after the San Benito Valley. Father Juan Crespí, in his expedition in 1772, named a small river in honor of San Benedicto (Saint Benedict), the patron saint of the married, and it is from the contraction of this name that the county took its name.
