Woodall Mountain, highest point in Mississippi, U.S., reaching an elevation of 806 feet (246 metres) above sea level. It lies in Tishomingo county in the extreme northeastern part of the state, just southwest of Iuka in the westernmost foothills of the southern Appalachians. During the American Civil War it was the site of the Battle of Iuka (September 19, 1862), at which a Union force under General William S. Rosecrans was initially repulsed by Confederates under General Sterling Price near its base. It is thought to have been named for Zephaniah H. Woodall, a former sheriff of Tishomingo county.
