was a French poet, writer and opera librettist who often wrote in collaboration with Michel Carré. He was a noted Parisian bon vivant and man of letters.
He also wrote the libretto for La Guzla de l'Émir, a one-act comic opera by Georges Bizet. This was never performed and probably destroyed.
He wrote the scenario for Léo Delibes' ballet Sylvia. Charles Gounod wrote incidental music to Barbier's play Jeanne d'Arc, and the libretto to Pyotr Ilyich Tchaikovsky's opera The Maid of Orleans was partially based on it.
