Valentine d'Aubigny is an opéra comique in three acts composed by Fromental Halévy to a libretto by Jules Barbier and Michel Carré.

[1][2] Valentine d'Aubigny was first and only time that Halévy used a libretto by Barbier and Carré, who went on to co-write several libretti for operas by other composers including Gounod and Ambroise Thomas.

[2] Their assessment that Halévy's music for Valentine was superior to Barbier and Carré's libretto echoed that of the critic Paul Scudo in his review of the 1856 premiere for Revue des deux Mondes.

He described the libretto as a "mediocre fable" and compared Barbier and Carré's work unfavorably to that of Eugène Scribe in the opéra comique genre.

The critic from La Presse théâtrale described the libretto as a "monster" which defied all logic, but concluded: Thank God, M. Halévy's music has enough power and charm to almost make us forget the nonsense of the piece.

[4]The Parisian music publisher Jules Heinz brought out several adaptations and extracts from the score, including its overture and 13 of its arias arranged for solo voice and piano by Auguste Charlot.

[5] However, despite its success with the audience on the opening night when Halévy was called to the stage by their applause,[4] the opera does not appear to have been revived after its initial run.

Over breakfast, he recounts to Gilbert that he has run away from Paris to escape marrying Sylvia, a popular actress at the Théâtre-Italien, to whom he has unwisely become engaged.

Amazed by this turn of events and determined to get to the bottom of it, Valentine agrees to Boisrobert's suggestion and tells him that her name is "Henriette".

Baron de Corisandre rubs his hands in glee while Sylvia collapses in a chair weeping for her lost love.
