Map of Benton County

Benton County is one of the 36 counties in the U.S. state of Oregon. As of 2023, about 99,355 people live there. Its main city and government center is Corvallis. The county is named after Thomas Hart Benton. He was a U.S. Senator who believed America should control the Oregon Country. Benton County is part of a larger group of cities around Portland. It is located in the beautiful Willamette Valley.

History of Benton County

Benton County was created on December 23, 1847. This happened by a decision of the Provisional Government of Oregon. The county got its name from Senator Thomas Hart Benton of Missouri. He strongly supported the idea of Manifest Destiny. This was a belief that the United States should expand its control across North America. Senator Benton thought the American government should control all of the Oregon Country.

When it was first formed, Benton County was much larger. It included all the land west of the Willamette River. It stretched south from Polk County all the way to the California border. It also went west to the Pacific Ocean.

The land in Benton County was originally home to Native American tribes. The Kalapuyas lived there, and the Klickitat tribe rented land for hunting. In 1855, the Native American claims to the land were given up in the Treaty of Dayton. Over time, parts of Benton County were used to create other counties. These included Coos, Curry, Douglas, Jackson, Josephine, Lane, and Lincoln Counties. This is how Benton County got its current shape.

The city of Marysville became the county seat in 1851. It was later renamed Corvallis. For a short time, Corvallis was even the capital of Oregon! In 1862, Corvallis became home to the Oregon State Agricultural College. Today, this school is known as Oregon State University.
