Theophilus Nash Buckingham (May 31, 1880 – March 10, 1971), commonly referred to as Nash Buckingham, was an American author and conservationist from Tennessee. He is perhaps most famous for writing a collection of short stories entitled De Shootinest Gent'man. He played college football for the Tennessee Volunteers, where he was captain and selected an All-Southern tackle in 1902. For many years after, Buckingham selected the All-Southern team for the Memphis Commercial Appeal. He was nominated though not selected for an Associated Press All-Time Southeast 1869-1919 era team.
