Alfonso und Estrella (Alfonso and Estrella), D 732, is an opera with music by Franz Schubert, set to a German libretto by Franz von Schober, written in 1822. Along with the later Fierrabras, composed in 1823, it marks Schubert's attempt to compose grand Romantic opera in German, departing from the Singspiel tradition. Unlike Fierrabras, it contains no spoken dialogue.
