Moses Wright Hannon (December 14, 1827 – June 3, 1897) was a Confederate States Army colonel during the American Civil War. In August 1864, he was assigned to duty as an acting brigadier general by General John Bell Hood, subject to appointment by Confederate President Jefferson Davis and confirmation by the Confederate Senate. Although Hannon commanded a brigade in the cavalry corps of the Army of Tennessee and in Major General Joseph Wheeler's cavalry corps from June 1864 until the end of the war, he never was officially appointed by Jefferson Davis and confirmed by the Confederate Senate to brigadier general rank.
