Auburn is a city in Nemaha County, Nebraska, United States. The population was 3,350 at the 2000 census. It is the county seat of Nemaha County. The City of Auburn is actually an incorporation of two towns. Calvert and Sheridan combined to form Auburn in 1882, in part to have the voting power to wrestle the county seat away from Brownville, Nebraska, a village located nine miles east. The incorporation was successful, and in 1883, Auburn was named the county seat.
The only person to be elected to the United States Congress as a member of the Prohibitionist Party, Charles Hiram Randall, was born in Auburn on July 23, 1865.
