Hygin-Edmond-Ludovic-Auguste Cavé (8 October 1796 – 30 March 1852) was a French attorney, journalist, and government official, as well as an occasional playwright and librettist, who often collaborated with Adolphe Dittmer under the pseudonym Jacques François de Fongeray. He is also sometimes referred to as Edmond Cavé. He is perhaps best known as the subject of a portrait by the French artist Ingres, which is on display at New York's Metropolitan Museum of Art.
