Adair County was named after the Adair family of the Cherokee tribe. One source says that the county was specifically named for Watt Adair, one of the first Cherokees to settle in the area.
Named for a prominent Cherokee family of which perhaps the most noted member was Col. William Penn Adair, who represented the Cherokee Nation at Washington from 1866 until his death in 1881.

The county was created in 1906 from the Goingsnake and Flint districts of the Cherokee Nation. There was a decade-long struggle over what town would become the county seat between Stilwell and Westville. When the county was formed, Westville was identified as the county seat, due partly to its location at the intersection of two major railroads: the Kansas City Southern Railway and the St. Louis - San Francisco Railway. The county seat was moved to Stilwell in 1910.
