Robert le diable (Robert the Devil) is an opera in five acts composed by Giacomo Meyerbeer between 1827 and 1831, to a libretto written by Eugène Scribe and Germain Delavigne. Robert le diable is regarded as one of the first grand operas at the Paris Opéra. It has only a superficial connection to the medieval legend of Robert the Devil. Robert continued as a favourite in opera houses all over the world throughout the nineteenth century. After a period of neglect, it began to be revived towards the end of the twentieth century.
