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.

Principal industries are wood products, agriculture, mining, and manufacturing.

Linn County is also home to the only emery mine in the United States, and the production of manufactured and motor homes.
