History and General Information

Oregon’s provisional legislature carved Benton County out of Polk County in 1847. It was named for U.S. Senator Thomas Hart Benton. At that time the boundaries began at the intersection of Polk County and the Willamette River, and ran as far south as the California border and as far west as the Pacific Ocean. Portions of Benton County were later taken to form Coos, Curry, Douglas, Jackson, Josephine, Lane and Lincoln counties.

Much of the nation’s research in forestry, agriculture, engineering, education and the sciences takes place at Oregon State University, located in the county seat of Corvallis. Along with the university, agriculture, wood products and electronics form the county’s economic base.
