Jean-Paul-André des Razins, marquis de Saint-Marc, (29 November 1728 – 11 September 1818) was an 18th-century French playwright and librettist. A former officer of the French Guards Regiment, Saint-Marc wrote the libretto for Adèle de Ponthieu, a 1772 opera by Jean-Benjamin de La Borde and Pierre Montan Berton, and a 1781 opera by Niccolò Piccinni. He wrote several opéra comique librettos and numerous pieces of fleeting poetry.
