'''''Cadmus et Hermione''''' is a ''tragédie en musique'' in a prologue and five acts by Jean-Baptiste Lully. The French-language libretto is by Philippe Quinault, after Ovid's ''Metamorphoses''. It was first performed on April 27, 1673, by the Paris Opera at the Jeu de paume de Béquet.
The prologue, in praise of King Louis XIV, represents him as Apollo slaying the Python of Delphi. The opera itself concerns the love story of Cadmus, legendary founder and king of Thebes, Greece, and Hermione (Harmonia), daughter of Venus and Mars. Other characters include Pallas Athene, Cupid, Juno, and Jupiter.
With ''Cadmus et Hermione'', Lully invented the form of the ''tragédie en musique'' (also known as ''tragédie lyrique''). From contemporary Venetian opera, Lully incorporated elements of comedy among the servants, elements which he would later avoid, as would subsequent reformers in Italian opera.
A contemporary transcription of the overture by Jean-Henri d'Anglebert remains a possible part of the harpsichord repertoire.
In early 2008, the French ensemble Le Poème Harmonique staged a performance of the opera in Paris and Rouen, among other places.
