Interior (Lakota: makȟóšiča otȟúŋwahe;[6] "Badlands village") is a town in Jackson County, South Dakota, United States.

[8] Norwegian immigrants George and Louis Johnson moved from Chamberlain, South Dakota to the banks of the White River just north of the Pine Ridge Reservation in 1883 to establish a way-station for freighting between Chamberlain and the Black Hills.

In 1907 and 1908, the town was moved two miles and half northwest along the White River to meet the Milwaukee Railroad.

Now with unlimited freshwater combined with being situated along the Milwaukee Railroad and near the Badlands, local committees seized the opportunity to use the town's advantage.

The events hosted cowboys from across the country and Native Americans in traditional clothing also participating.

[9] Interior is located along the White River approximately one mile from Badlands National Park.

The racial makeup of the town was 70.2% White, 19.1% Native American, and 10.6% from two or more races.

There were no families and 8.8% of the population living below the poverty line, including no residents younger than eighteen and none over 64.
