Il Guarany is an opera ballo composed by Antônio Carlos Gomes, based on the novel O Guarani by José de Alencar. Its libretto, in Italian rather than Gomes' native Portuguese, was written by Antonio Scalvini and Carlo D'Ormeville. The work is notable as the first Brazilian opera to gain acclaim outside Brazil. Maria Alice Volpe has analysed the historical subtext of the indianism movement behind Il Guarany.
