Griselda is a dramma per musica in three acts that was composed by Antonio Vivaldi. The opera uses a revised version of the 1701 Italian libretto by Apostolo Zeno that was based on Giovanni Boccaccio's The Decameron. The celebrated Venetian playwright Carlo Goldoni was hired to adapt the libretto for Vivaldi. The opera was first performed in Venice at the Teatro San Samuele on 18 May 1735.
