Armida Abbandonata (Armida Abandoned) is an opera in three acts by the Italian composer Niccolò Jommelli.
The libretto, by Francesco Saverio De Rogatis, is based on the epic poem Jerusalem Delivered by Torquato Tasso.
The opera was first performed at the Teatro San Carlo, Naples, on 30 May 1770.
The young Wolfgang Amadeus Mozart was in the audience.
Nevertheless, despite a lukewarm reception at its premiere, Armida abbandonata was widely performed throughout Italy in the following years.
