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. Like Fierrabras (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.

Franz Schubert's best-known music for the theatre is his incidental music for Rosamunde. Less successful were his many opera and Singspiel projects. On the other hand, some of his most popular Lieder, like "Gretchen am Spinnrade," were based on texts written for the theatre.

Der Graf von Gleichen D 918 is an unfinished 1827 opera in two acts by Franz Schubert after a libretto by Eduard Bauernfeld.

Franz Schubert (31 January 1797 – 19 November 1828), a Viennese composer of the late Classical to early Romantic eras, left a very extensive body of work notwithstanding his short life. He wrote over 1,500 items, or, when collections, cycles and variants are grouped, some thousand compositions. The largest group are his over six hundred Lieder for solo voice and piano. He composed nearly as many piano pieces, and further some 150 part songs, some 40 liturgical compositions (including several masses) and around 20 stage works like operas and incidental music. His orchestral output includes thirteen symphonies (seven completed) and several overtures. Schubert's chamber music includes over 20 string quartets, and several quintets, trios and duos. Otto Erich Deutsch compiled the first comprehensive catalogue of Schubert's works and published it in 1951 as Schubert: Thematic Catalogue of all his Works in Chronological Order. A revised edition appeared in German in 1978. Later editions of the catalogue contained minor updates. Publication of Schubert's compositions started during his lifetime, by opus number. After the composer's death, posthumous opus numbers continued to be assigned to new publications of his work until 1867 (Op. post. 173). Meanwhile, publications without opus number had also started. For instance, from shortly after the composer's death, the many songs in Diabelli's fifty Nachlaß-Lieferung (installment from the heritage) editions. There are two attempts to publish everything Schubert has composed in a single edition: From 1884 to 1897 Breitkopf & Härtel published twenty-two series of Franz Schubert's Werke: Kritisch durchgesehene Gesammtausgabe, known as the Alte Gesamt-Ausgabe (AGA, the former complete edition). From 1965 Dover Publications started to reprint this edition, and later it was made available at the IMSLP website. The Neue Schubert-Ausgabe (NSA), also known as the New Schubert Edition (NSE), is published by Bärenreiter (Kassel). Plans for this edition began as early as 1963, with the foundation of the International Schubert Society, headquartered at the University of Tübingen, Germany. 81 of the edition's projected 101 volumes were published by early May 2015, and it is scheduled to conclude in 2027. Websites such as Schubert Online (schubert-online.at) provide facsimiles (scans) of Schubert's autographs and of other manuscripts and early editions of his work. Texts of Schubert's vocal music can be published without the music, for instance his Lieder (songs) at the LiederNet Archive website.

Der vierjährige Posten, D 190, is a one-act singspiel by Franz Schubert to a libretto by Theodor Körner written for Carl Steinacker's (1784–1814) opera of the same title that premiered in 1813 in Vienna's Theater an der Wien. Written in 1815 when Schubert was 18 years old, it was first performed on 23 September 1896, 67 years after Schubert's death, at the Dresden Court Opera. The work consists of an overture and eight numbers for soprano, three tenors, bass, one spoken role, mixed choir and orchestra: Ouvertüre Introduktion: Heiter strahlt der neue Morgen Duett: Du guter Heinrich! Ach, was wir beide doch glücklich sind! Terzett: Mag dich die Hoffnung nicht betrügen! Quartett: Freund, eilet euch zu retten! Arie: Gott! Gott! höre meine Stimme (a version for voice and piano is also extant) Marsch und Soldatenchor: Lustig in den Kampf Ensemble: Um Gotteswillen, er ist verloren! Finale: Schöne Stunde, die uns blendet

Franz Schubert's best-known music for the theatre is his incidental music for Rosamunde. Less successful were his many opera and Singspiel projects. On the other hand, some of his most popular Lieder, like "Gretchen am Spinnrade," were based on texts written for the theatre.

Die Freunde von Salamanka D. 326, is an 1815 Singspiel in two acts by Franz Schubert to a libretto by Johann Mayrhofer. The opera is set at the beginning of the 19th century in Salamanca, Spain. It consists of an overture and eighteen numbers, and is set for three sopranos, three tenors, six basses, mixed choir and orchestra: Act 1Overture Act 2

Die Verschworenen, also known as Der häusliche Krieg (D 787) is an 1823 one-act singspiel by Franz Schubert after a libretto by Ignaz Franz Castelli with spoken dialogue by the composer. Castelli's libretto was based on Lisistrata, ou Les Athéniennes, Comédie en un acte et en prose, mêlée de vaudevilles by François-Benoît Hoffman, which had premiered at the Théâtre Feydeau in Paris in 1802. The French play in turn was based on Lysistrata by Aristophanes (411 BCE).

Die Zwillingsbrüder (The Twin Brothers, D. 647) is a one-act Singspiel (sometimes also described as a Posse mit Gesang) composed by Franz Schubert in 1819 on a libretto by Georg Ernst von Hofmann. Die Zwillingsbrüder was first performed at the Kärntnertortheater on June 14, 1820. Hofmann based the libretto on the 1818 French vaudeville Les deux Valentin (The Two Valentines) by Marc-Antoine Madeleine Désaugiers and Michel-Joseph Gentil de Chavagnac (1770–1846). Die Zwillingsbrüder, like Schubert's other operatic works, met with limited success both at the work's inception and over time. Critics attribute this to the weakness of the libretto as well as to a mismatch between the lightness of the subject matter and the refined nature of Schubert's music. In this work, Schubert's music often approaches the style of Mozart, evoking for instance Die Zauberflöte.

Fierrabras, D 796, is a three-act German opera with spoken dialogue written by the composer Franz Schubert in 1823, to a libretto by Joseph Kupelwieser, the general manager of the Theater am Kärntnertor (Vienna's Court Opera Theatre). Like Alfonso und Estrella (1822), it marks Schubert's attempt to compose a grand Romantic opera in German, departing from the Singspiel tradition. It had to wait until 1897 for a (relatively) complete performance.
