Linn County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 128,610. The county seat is Albany. The county is named in honor of Lewis F. Linn, a U.S. Senator from Missouri who advocated the American settlement of the Oregon Country. Linn County comprises the Albany, OR Metropolitan Statistical Area, which is included in the Portland-Vancouver-Salem, OR-WA Combined Statistical Area. It is located in the Willamette Valley. In 2010, the center of population of Oregon was located in Linn County, near the city of Lyons.


On December 28, 1847 the Provisional Legislature created Linn County from the southern portion of Champoeg (later Marion) County. The boundaries were altered in 1851 and 1854 with the creation of Lane and Wasco Counties. The county seat was originally located in Calapooia (later known as Brownsville), but in 1851 the Territorial Legislature passed an act establishing Albany as the county seat. A special election in 1856 reaffirmed Albany as the county seat.


According to the U.S. Census Bureau, the county has a total area of 2,309 square miles (5,980 km2), of which 2,290 square miles (5,900 km2) is land and 19 square miles (49 km2) (0.8%) is water.
