Prince Friedrich August Eberhard of Württemberg (full German name: Friedrich August Eberhard, Prinz von Württemberg; 24 January 1813, Stuttgart, Kingdom of Württemberg – 12 January 1885, Ban de Teuffer, Zehdenick, Province of Brandenburg, Kingdom of Prussia) was a royal Prussian Colonel General of the Cavalry with the rank of Generalfeldmarschall and Kommandierender General of the Guards Corps for more than 20 years. August was a member of the House of Württemberg and a Prince of Württemberg by birth.

After 16 years of military service to the Kingdom of Württemberg in 1831, August was promoted to Rittmeister in the First Cavalry Regiment. In April 1831, August was granted permission by his uncle William I of Württemberg to serve in the Prussian Army.

In the Prussian Army, August was assigned initially to the Regiment Gardes du Corps and a year later he was promoted to Major. In 1836, August was further promoted to Lieutenant Colonel and in 1838 to Colonel. August served as a Commando for four years in the Guards Cuirassiers. In 1844, as Major General, August assumed the leadership of the 1st Guards Cavalry Brigade and as early as 1850 he was promoted to Lieutenant General. With a brief interruption of two years from 1854 to 1856, he commanded the 7th Division in Magdeburg, but remained loyal to the cavalry. In September 1857, August served as Commanding General of III Corps, but changed as early as 3 June 1858 to the Commanding General for the Guards Corps. This position he held for 20 years.
