Corvallis-Benton County Public Library, Public library in Corvallis, United States.

Corvallis-Benton County Public Library is a public library system operating multiple locations throughout Benton County. Each branch provides books, audiobooks, magazines, and digital content, with an online catalog for managing accounts and requesting materials.

Benton County's first library was a private circulating collection run in Corvallis in the 1860s by J.W. Souther, who advertised his 730 volumes in the Corvallis Gazette at $5 a year. In December 1872 railroad investor Dr. J. R. Bayley offered a room in a brick building he was putting up if a permanent library association formed. The present building was designed by Pietro Belluschi in 1932, with a modest expansion in 1965 and a major reconfiguration and expansion in 1992.

The library hosts community events and programs throughout the year, featuring local authors and celebrations honoring different cultures. These gatherings turn the space into a meeting place where readers and neighbors come together.

Visitors can use the online catalog to search for materials, manage their accounts, and request new books from the collection. The library locations are accessible spaces open during regular hours and welcome readers of all ages.

The library's motto is "Enrich, excite, explore!" The Japanese-language source gives a different motto, "Bringing people and information together." The building was designed by Pietro Belluschi in 1932, with expansions in 1965 and 1992. Hennen's American Public Library Ratings placed it among the top ten U.S. libraries by population served in 1997, 1999 and 2000.
