Medea's Dance of Vengeance is a composition (1955, Op. 23a) by the American composer Samuel Barber, derived from his earlier ballet suite Medea. Barber first created a seven-movement concert suite from this ballet (Medea, Op. 23), and five years later reduced this concert suite down to a single-movement concert piece using what he felt to be the strongest portions of the work. He originally titled it Medea's Meditation and Dance of Vengeance, but shortly before his death, he changed the title to simply Medea's Dance of Vengeance.
