La fiera di Venezia (The fair in Venice) is a three-act opera buffa, described as a commedia per musica, by Antonio Salieri, set to an Italian libretto by Giovanni Gastone Boccherini [it] (brother of the composer Luigi Boccherini).

The opera premiered with great success on 29 January 1772 at the Burgtheater in Vienna.

[1][2] La fiera di Venezia turned out to be one of Salieri's best regarded works and during his lifetime was staged more than thirty times throughout Europe.

[3] In 1773, Mozart wrote fortepiano variations to the aria "Mio caro adone".

In the movie Amadeus, Mozart refers to the piece when introducing himself to Salieri.
