Vanessa is an opera in three (originally four) acts by Samuel Barber with an original English libretto by Gian-Carlo Menotti. It was composed in 1956–1957 and was first performed at the Metropolitan Opera in New York City on January 15, 1958, in a production designed by Cecil Beaton and directed by Menotti. Barber revised the opera in 1965, reducing the four acts to the three-act version most commonly performed today.
