Polyeucte martyr is a drama in five acts by French writer Pierre Corneille. It was finished in December 1642 and debuted in October 1643. It is based on the life of the martyr Saint Polyeuctus (Polyeucte).
In 1878 it was adapted into an opera by Charles Gounod, with the assistance of the librettist Jules Barbier. The opera was not a success and is rarely performed except for a number of arias including "Source délicieuse" and the barcarolle "Nymphes attentives". Other works based on the play include a ballet by Marc-Antoine Charpentier(1679), the opera Poliuto (1838) by Donizetti (adapted into French by Scribe as Les martyrs), an overture by Paul Dukas (1891) and a composition by Edgar Tinel.
