Maximilian Andreas of Dietrichstein (14 April 1638 – 4 December 1692), was a German prince member of the House of Dietrichstein.
He was the eleventh child and fourth (but third surviving) son of Maximilian, 2nd Prince of Dietrichstein zu Nikolsburg, and his first wife Anna Maria, a daughter of Karl I, Prince of Liechtenstein and Duke of Troppau and Jägerndorf.

On 18 January 1663, he married with Maria Justina (20 February 1647 – 21 April 1696), a daughter of Edmund III of Schwarzenberg, Seigneur de Bierset, d'Hierges, de Champlon and Countess Marie d'Arschot de Riviere.
