La magicienne (The Sorceress) is a grand opera in five acts composed by Fromental Halévy. The libretto by Jules-Henri Vernoy de Saint-Georges is based on stories surrounding the European folk figure Melusine, especially Coudrette's 15th-century Roman de Mélusine. The opera premiered on 17 March 1858 at the Théâtre de l'Académie Impériale de Musique in Paris. It had a mixed reception and after its initial run of 45 performances was not heard again until it was revived in a heavily cut concert version performed in Montpellier in 2011.
