Lamoral II Claudius Franz, Count of Thurn and Taxis (14 February 1621 (baptized) – 13 September 1676) was a German nobleman and Imperial Postmaster. He took over the post of Imperial Postmaster General from his mother when he came of age in 1646. He obtained permission from the Emperor in 1650 to change his family name to von Thurn, Valsassina und Taxis, but then opted for the shorter von Thurn und Taxis (or de la Tour et Tassis in French). He and his mother were instrumental in the organization of the Imperial postal system. After the end of the Thirty Years' War, he successfully competed against the many postal systems of the German states. He was, however, unable to regain a legal monopoly. He also participated in the negotiations that led to the Treaty of Westphalia.
