Marie-Julie Boulanger, née Marie-Julie Halligner, was a French mezzo-soprano. She performed her entire career under the stage name Mme Boulanger, appearing in the world premieres of Le maître de chapelle, L'ambassadrice, Le domino noir, and La fille du régiment.

Le domino noir is an opéra comique by the French composer Daniel Auber, first performed on 2 December 1837 by the Opéra-Comique at the Salle de la Bourse in Paris. The libretto to the three-act piece is by Auber's usual collaborator, Eugène Scribe. It was one of Auber's most successful works, clocking up 1,207 performances by 1909. It received its UK premiere in 1838 and appeared in the USA the following year. Some of Auber's music has a Spanish flavour to reflect its setting.
