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 Itrani guerrilla leader Michele Pezza, active in southern Italy in the period 1800-1806, who went under the name of Fra Diavolo ("Brother Devil").
