Adair County was formed on December 11, 1801, from sections of Green County. Columbia was chosen as the county seat the following year and the first courthouse was built in 1806.

The county was named in honor of John Adair, a veteran of the Revolutionary War and Northwest Indian War. Later he commanded Kentucky troops in the Battle of New Orleans. He served as the eighth Governor of Kentucky. This was the 44th of Kentucky’s 120 counties to be organized.

After the American Civil War, a gang of five men, believed to include Frank and Jesse James from Missouri, robbed the Bank of Columbia of $600 on April 29, 1872. They killed the cashier, R.A.C. Martin, in the course of the robbery.

The courthouse on the Columbia town square, completed in 1884, replaced the original 1806 courthouse.
