Simon Boccanegra (Italian: [siˈmom bokkaˈneːɡra]) is an opera with a prologue and three acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on the play Simón Bocanegra (1843) by Antonio García Gutiérrez, whose play El trovador had been the basis for Verdi's 1853 opera, Il trovatore.
