Cendrillon (Cinderella) is a French opera in three acts by the Maltese-born composer Nicolas Isouard. It takes the form of an opéra comique with spoken dialogue between the musical numbers, although its authors designated it an opéra féerie. The libretto, by Charles Guillaume Etienne, is based on Charles Perrault's fairy tale Cinderella. The work was first performed by the Opéra-Comique at the Salle Feydeau in Paris on 22 February 1810. Cendrillon was a success throughout Europe until its popularity was eclipsed by that of Rossini's opera on the Cinderella theme, La Cenerentola (1817).
