Bon Homme County was created in 1862. "Bon Homme" was first used by Lewis and Clark in 1804 as the name for a 2,000 acre island in the Missouri River. When settlers arrived in the late 1850s they borrowed the name, and when the county was created it was named for the village of Bon Homme. A proposal to change the county name to "Jefferson" in 1865 was rejected. The French word "bonhomme" means "good man." The original island is now submerged under Lewis and Clark Lake. The village of Bon Homme was the original county seat until 1885, when it moved to Tyndall.

Bon Homme County is the point of origin for the Siberian alien, Kali tragus, a type of tumbleweed, first reported here in 1877, probably introduced in a shipment of flax seed from Ukraine.
