Quitman County is a county located in the southwestern part of the U.S. state of Georgia. As of the 2020 census, the population was 2,235, making it the second-least populous county in Georgia. The county seat is Georgetown. The county was created on December 10, 1858, and named after General John A. Quitman, leader in the Mexican–American War, and once Governor of Mississippi. In November 2006, residents voted to consolidate the city government of Georgetown and the county government of Quitman into a consolidated city-county.

John Anthony Quitman was an American lawyer, politician, and soldier. As President of the Mississippi Senate, he served one month as Acting Governor of Mississippi as a Whig. He was elected governor in 1849 as a Democrat, and served from January 10, 1850, until his resignation on February 3, 1851, shortly after his arrest for violating U.S. neutrality laws. He was strongly pro-slavery and a leading Fire-Eater.
