Fra Diavolo, ou L'hôtellerie de Terracine (Fra Diavolo, or The Inn of Terracina) is an opéra comique in three acts by the French composer Daniel Auber, from a libretto by Auber's regular collaborator Eugène Scribe. It is loosely based on the life of the Neapolitan bandit Michele Pezza, active in southern Italy in the period 1800-1806, who went under the name of Fra Diavolo ("Brother Devil").
The opera was first performed by the Opéra-Comique at the Salle Ventadour in Paris on 28 January 1830 and an Italian version was prepared by Auber and Scribe for performance in London in 1857. This contained new recitatives and arias, as well as expanding the roles of Fra Diavolo's accomplices.
