La Gioconda is an opera in four acts by Amilcare Ponchielli set to an Italian libretto by Arrigo Boito, based on Angelo, tyran de Padoue, a play in prose by Victor Hugo, dating from 1835.

First performed in 1876, La Gioconda was a major success for Ponchielli, as well as the most successful new Italian opera between Verdi's Aida (1871) and Otello (1887). It is also a famous example of the Italian genre of Grande opera, the equivalent of French Grand-Opéra.

Ponchielli revised the work several times; the version that is played today was first given in 1880. It is one of only a few operas that features a principal role for each of the six major voice types. This live 1979 recording stars Montserrat Caballe and Jose Carreras. Jesus Lopez-Cobos conducts.
