Benton County is one of the 36 counties in the U.S. state of Oregon. As of the 2010 census, the population was 85,579. Its county seat is Corvallis. The county was named after Thomas Hart Benton, a U.S. Senator who advocated American control over the Oregon Country. Benton County is designated as the Corvallis, OR Metropolitan Statistical Area, which is included in the Portland-Vancouver-Salem, OR-WA Combined Statistical Area. It is in the Willamette Valley.
Benton County was created on December 23, 1847 by an act of the Provisional Government of Oregon. The county was named after Democratic Senator Thomas Hart Benton of Missouri, an advocate of the doctrine of Manifest Destiny and the belief that the American government should control the whole of the Oregon Country. At the time of its formation the county included all the country west of the Willamette River, south of Polk County and running all the way to the California border in the south and the Pacific Ocean in the west.
The county was created out of lands originally inhabited by the Klickitat, who rented it from the Kalapuyas for use as hunting grounds. All aboriginal claims to land within Benton County were ceded in the Treaty of Dayton in 1855. Portions of Benton County were taken to form Coos, Curry, Douglas, Jackson, Josephine, Lane and Lincoln Counties, leaving Benton County in its present form.
The city of Marysville, later renamed Corvallis, was made the county seat in 1851. The city briefly was the capital of Oregon. In 1862 Corvallis became the site of the Oregon State Agricultural College, known today as Oregon State University.
According to the U.S. Census Bureau, the county has a total area of 679 square miles (1,760 km2), of which 676 square miles (1,750 km2) is land and 2.7 square miles (7.0 km2) (0.4%) is water. It is the fourth-smallest county in Oregon by land area and third-smallest by total area.

Politics and government
For a long time Benton County strongly favored the Republican Party. Along with Riverside County in California it was one of only two counties in the Pacific States to be held by Herbert Hoover in 1932. As late as 1960 Benton was the most Republican county in the traditionally Republican state of Oregon, which at that point had never supported a Democrat other than FDR for President except for 1912 when the Republican Party was divided and a very narrow victory in 1868. Up to 1984 Benton County had voted for a Democratic Presidential candidate only four times, in the above-mentioned 1868 election plus the national Democratic landslides of 1912, 1936 and 1964. In 1964, Lyndon Johnson became the first Democrat to win an absolute majority of the county's vote since Horatio Seymour.
The Republican edge in the county narrowed from the 1970s onward, culminating when it swung from a five-point victory for Ronald Reagan in 1984 to a nine-point victory for Michael Dukakis in 1988. Since then, Benton County has become a strongly Democratic county, and is usually the second-strongest Democratic bastion in the state, behind only Multnomah County (Portland). This is largely due to the leanings of Oregon State's student body and staff, closely tracking with Democratic gains in other counties influenced by college towns. No Republican has come within nine percentage points of carrying Benton County since 1988, and Barack Obama and Hillary Clinton have won the county by over thirty percentage points during each of the last three presidential elections.
Since 1972, Benton County has been a home rule county, meaning that the citizens have full control over the county charter, rather than using a standard charter issued by the state. The voters have chosen to eliminate the traditional elected county offices of Assessor, Treasurer, Surveyor, Justice of the Peace, and Clerk. Currently, they only elect three County Commissioners and a Sheriff.
The three current Benton County Commissioners are Chair Pat Malone, Xanthippe Augerot, and Annabelle Jaramillo. They are all members of the Democratic Party and have served since 2019, 2017, and 2001; respectively. Jaramillo and Augerot's current terms expire in January 2021, while Malone's is up in January 2023.
The current Benton County Sheriff is Scott Jackson. He was appointed to the office as of July 1, 2013 to fill the remainder of the term of retiring sheriff Diana Simpson, the first elected female sheriff in Oregon. He was re-elected in 2014 and 2018.
Along with Oregon State University, agriculture, lumber, wood products, and some printing technology research and development form the economic base of the county. A substantial portion of the nation's research in forestry, agriculture, engineering, education and the sciences takes place at OSU.
