Jean-François Cussy, better known as Champmêlé, (28 October 1745 – 9 July 1806) was an 18th-century French actor and theatre manager.
A lawyer by the Parlement of Paris, he seems to have entered the theatrical career in Normandy in his late twenties, probably leading a small touring company.
Engaged at the Théâtre de la Monnaie in Brussels for the 1786–1787 season, he played kings and noble fathers.
Hired by the Comédie-Italienne in Paris, he made his debut 25 October 1791 in La Fausse Magie by Marmontel and Grétry, and in Blaise et Babet by Monvel and Dezède.
Afterwards, Champmêlé was director of the Théâtre de la Monnaie in 1794–1795, then in 1798–1799 in association with Marc d'Oberny.
