Plutus is a three-act opéra comique by Charles Lecocq, with a libretto by Albert Millaud and Gaston Jollivet. It was first presented at the Opéra-Comique, Paris, on 31 March 1886; it was not a success and was taken off after eight performances. This was the first and last opera Lecocq wrote for the Opéra-Comique. The story, with an ancient Greek setting, is loosely based on a play by Aristophanes, and portrays the damage that wealth can do to the course of true love.
