Un mari à la porte (A Husband at the Door) is an opérette in one act of 1859 with music by Jacques Offenbach. The French libretto was by Alfred Delacour (Alfred Charlemagne Lartigue) and Léon Morand. Un mari à la porte was premiered by the Théâtre des Bouffes Parisiens at the Salle Lacaze in Paris. The premiere occurred shortly after the first operatic work with words by Eugène Labiche, and Yon discerns a similarity in the vaudevillian plot of Un mari à la porte with popular works by Labiche. The work remained in the repertory of the Bouffes Parisiens for some time.
