Maximilian Philipp Hieronymus, Duke of Bavaria-Leuchtenberg

Maximilian Philipp Hieronymus (30 September 1638, Munich - 20 March 1705, Turkheim) was a German prince.

He was the second of two sons born to the Elector Maximilian I and his wife Archduchess Maria Anna of Austria.

Maximilian also acquired the lordships of Angelberg and Mattsies from the Fuggers.

In 1668 he married, at the Château-Thierry, Mauricienne Fébronie de La Tour d’Auvergne (1652-1706) (a.k.a.

Princesse d'Evreux) daughter of Frédéric Maurice, sovereign Duke of Bouillon and his wife, Countess Eleonore-Catherine van Bergh, but the marriage remained childless and on Maxilimilian's death his duchy was re-absorbed into the domains of his nephew, Elector Maximilian II.
