Benoit-Louis Prevost (b. 1747, d. 1804) was a French engraver and skilled craftsman. During his studies, under the tutelage of Jean Ouvrier, he engraved about 60 of Charles Nicolas Cochin’s drawings with great precision and skill.

Some notable works of his include the 1765 frontispiece of the Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers (or simply the “Encyclopédie”) and the Allégorie pour l'édition in-4 de l'abrégé chronologique de l'histoire de France du président Hénault. He made portraits of Louis XV of France, Marie Antoinette, Armand Thomas Hue de Miromesnil, Louis XVI of France, Joseph Ignace Guillotin, and a portrait entitled Voltaire merchant dans son jardin (“Voltaire working in his garden”).
