Harding County, South Dakota was established in 1881 and named after J.A. Harding, Speaker of the House of Representatives of Dakota Territory. An 1898 general election changed the boundaries of Butte County to include Harding County. In 1908, it was separated from Butte County and again became Harding County with its present boundaries. Buffalo became the county seat in November of 1910. A new courthouse was built in 1997 to replace the original one in 1909.
