Ballo della Regina is a one-act neoclassical ballet choreographed by George Balanchine to music by Giuseppe Verdi. It is a set of variations set to ballet music (titled La Peregrina) that Verdi cut from Act 3 of the original 1867 version of his opera Don Carlos. Its premiere performance was on 12 January 1978, by the New York City Ballet at New York State Theater in Lincoln Center.
