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,[1] 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.

Voltaire, receive the crown That one just presented to you; It is beautiful to deserve it, When it is France who gives it!

The mansion in the city where he lived and died was registered as Monument historique 23 July 1921.
