La poupée (The Doll) is an opéra comique in a prelude and three acts composed by Edmond Audran with a libretto by Maurice Ordonneau. The libretto was based on E.T.A. Hoffmann's Der Sandmann, about a friar who falsely promises to marry his rich uncle's daughter to fool his uncle into giving money to the monastery; the scheme involves creating a doll that looks like the daughter. The uncle's daughter, however, turns the scheme on its head and fools the friar into actually marrying her by substituting herself for the doll.
