Maria egiziaca

 ("Saint Mary of Egypt") is an opera in one act, in three episodes, by the Italian composer Ottorino Respighi. The libretto, by Claudio Guastalla, is based on a Medieval life of Saint Mary of Egypt, contained in the translation into the vernacular of the "Vitae Patrum" written by Domenico Cavalca.
The work was originally intended as a concert piece although it has been fully staged in some revivals. It was first performed at Carnegie Hall, New York City, on 16 March 1932. The first stage performance was at the Teatro Goldoni in Venice on 10 August 1932. Both the language of the libretto and the music employ archaism; Respighi's score contains stylistic echoes of Gregorian chant, Renaissance music and Monteverdi.
