Ben Barton (June 8, 1823 – January 1, 1899), often erroneously referred to as Benjamin Barton, was a prominent landowner and white settler of the San Bernardino Valley in southern California. Educated as a doctor in the East, he migrated to Southern California in 1854. A few years later, he purchased a large tract of land in Rancho San Bernardino. He served various political roles in state and local government. After retiring from his medical practice, he became a rancher and vintner, and had a large mansion built for his family. His sons also became prominent local politicians and businessmen.
