Count Ferdinand Ernst Joseph Gabriel von Waldstein und Wartenberg (24 March 1762 – 26 May 1823) was a German nobleman and patron of the arts. A member of the Bohemian House of Waldstein and an early patron of Ludwig van Beethoven, his political and military roles included the office of a Geheimrat in Bonn, commander (Komtur) of the Teutonic Order, and (briefly) colonel of a light infantry regiment that he had raised.
