Le dilettante d'Avignon (English: The Dilettante of Avignon) is an 1829 opéra comique in one act by Fromental Halévy, to a libretto by his brother Léon Halévy, based on an uncompleted work by François-Benoit Hoffmann.

It was the composer's first popular success, since it was his first venture into opera after the relative failure in the previous year of Clari.

Léon Halévy was offered the uncompleted libretto of Le dilettante by Hoffmann's son.

[1] He developed it into a witty satire on Italian music, and the work was premiered at the Opéra-Comique on 7 November 1829.

The libretto contains some sly fun about the composer; like the imposter 'Imbroglio', Fromental Halévy himself was a graduate of the Prix de Rome, and was at the time of the premiere a 'chef du chant' (singing director), in this case at the Paris Opéra.
