Léon Guillaume (du) Tillot[1] (Bayonne, 22 May 1711 — Paris, 13 December 1774) was a French politician infused with liberal ideals of the Enlightenment, who from 1759 was the minister of the Duchy of Parma under Philip, Duke of Parma and his wife Princess Louise-Élisabeth of France. At a time when both Bourbon France and Bourbon Spain thought of Parma as a strategic point of interest, Tillot favoured French policies abroad and wide-ranging reforms within the Duchy of Parma. He was made marchese di Felino.
Tillot's career was of his own making. The son of a valet de chambre, he studied at the Collège des Quatre-Nations in Paris, then went to the court of Charles III of Spain; after Charles' departure to be King of Sicily, Tillot was attached to the household of Philippe de Bourbon, whose private secretary and treasurer he became. He organised fêtes for Philippe at Chambéry and elsewhere.
