La figlia di Iorio (The Daughter of Iorio), sometimes written as La figlia di Jorio, is an opera in three acts by Alberto Franchetti to a libretto by Gabriele D'Annunzio. The libretto is a very close rendering of D'Annunzio's play of the same name. La figlia di Iorio premiered at La Scala on 29 March 1906, conducted by Leopoldo Mugnone. Although the play, which had premiered two years earlier, was considered one of D'Annunzio's greatest works, the opera did not achieve a comparable success and has been rarely performed since its day.
