Clovis is a city in Fresno County, California, United States. It was established in 1890 as a freight stop for the San Joaquin Valley Railroad by a group of Fresno businessmen and Michigan railroad speculator Marcus Pollasky. The railroad bought the land from two farmers and named the station after one of them, Clovis Cole. Pollasky then developed a town on the site, also named Clovis.
