Robert le diable is an opera in five acts composed by Giacomo Meyerbeer between 1827 and 1831, to a libretto written in French 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.

Giacomo Meyerbeer was a German opera composer, "the most frequently performed opera composer during the nineteenth century, linking Mozart and Wagner". With his 1831 opera Robert le diable and its successors, he gave the genre of grand opera 'decisive character'. Meyerbeer's grand opera style was achieved by his merging of German orchestra style with Italian vocal tradition. These were employed in the context of sensational and melodramatic libretti created by Eugène Scribe and were enhanced by the up-to-date theatre technology of the Paris Opéra. They set a standard which helped to maintain Paris as the opera capital of the nineteenth century.
