Jean-Baptiste-Marie Chamouin (1768 - 18xx) was a French engraver active in the late 18th and early 19th centuries. Chamouin was born in Paris. He mastered engraving working at the Dépôt de Guerre, and went on to private commercial work in geographical publication. He engraved with Jean Baptiste Tardieu (1768 - 1837), Pierre M. Lapie (fl. 1779 - 1850), and Conrad Malte-Brun (1755 - 1826), among others. His offices, at least in 1845, were at 29 Rue de la Harpe, Paris.
