Nemaha County is a county in the U.S. state of Nebraska. As of the 2010 United States Census, the population was 7,248. Its county seat is Auburn.

In the Nebraska license plate system, Nemaha County is represented by the prefix 44 (it had the forty-fourth-largest number of vehicles registered in the county when the license plate system was established in 1922).


The county forms the core of the Nemaha Half-Breed Reservation formed in the Fourth Treaty of Prairie du Chien in 1830 as land for the offspring of traders and Native Americans. The grounds of modern Indian Cave State Park mark where the county's first community -- St. Deroin, Nebraska was founded in 1853 by members of the reservation as a trading post on the Missouri River. When white settlement was permitted in the Kansas-Nebraska Act of 1854 it was part of Forney County (named for U.S. cabinet member John W. Forney) which stretched along the Little Nemaha River from the Missouri River to west of Lincoln, Nebraska. In 1855 Nemaha County was formally founded with Brownville as its county seat. Johnson County was initially part of Nemaha but was subsequently spun off.

Brownville was the biggest city in Nebraska at the time and several firsts occurred in the county including: in 1861 the first state normal school which was founded at what today is Peru State College and Daniel Freeman filing the first claim under the Homestead Act for land on January 1, 1863 at the Brownville land office.

The Nebraska State Fair was held in the county at Brownville in 1870-1871.

In 1883 the county seat was moved to Auburn.

In 1974 the Cooper Nuclear Station was commissioned south of Brownville.


According to the U.S. Census Bureau, the county has a total area of 410 square miles (1,100 km2), of which 407 square miles (1,050 km2) is land and 2.2 square miles (5.7 km2) (0.5%) is water. Nemaha County is covered with rolling hills and farmland.

Most of the eastern border follows the Missouri River bordering Atchison County, Missouri. In the county's extreme northeast corner, the border follows the river's former course, lying nearly two miles (3 km) east of the present-day channel. This de facto enclave is McKissick Island.
