Vesperae solennes de confessore (Solemn Vespers for a Confessor), K. 339, is a sacred choral composition, written by Wolfgang Amadeus Mozart in 1780. It is scored for SATB choir and soloists, violin I, violin II, 2 trumpets, 3 trombones colla parte, 2 timpani, and basso continuo (violoncello, double bass, and organ, with optional bassoon obbligato).

The setting was composed for liturgical use in the Salzburg Cathedral. The title "de confessore" was not Mozart's own, and was added by a later hand to his manuscript. It suggests that the work was intended for vespers held on a specific day on the liturgical calendar of saints ("confessors"); however, the saint in question has not been conclusively established if there even was one. This was Mozart's final choral work composed for the cathedral.

Ave verum corpus (Hail, true body), (K. 618), is a motet in D major composed by Wolfgang Amadeus Mozart in 1791. It is a setting of the Latin hymn Ave verum corpus. Mozart wrote it for Anton Stoll, a friend who was the church musician of St. Stephan in Baden bei Wien. The motet was composed for the feast of Corpus Christi; the autograph is dated 17 June 1791. It is scored for SATB choir, string instruments and organ.
