Polixène (Polyxena) is an opera by the French composer Antoine Dauvergne, first performed at the Académie Royale de Musique (the Paris Opéra) on 11 January 1763.
The libretto, by Nicolas-René Joliveau, is based on Euripides and tells the story of the Trojan princess Polyxena.
Juno hates the Trojans and would not wish to see a marriage uniting the son of Achilles with the daughter of Hecuba.
Pyrrhus' friend Telephus is also a rival for Polyxena’s love and he has Hecuba's blessing.
Finally, Hecuba is won over and consents to the marriage of Polyxena and Pyrrhus.
