Giovanni Schmidt (c. 1775 in Livorno – c. after 1839 in Naples) was an Italian librettist.

He moved to Naples while he was still young and stayed there for the rest of his life. Between 1800 and 1839 he wrote libretti for 45 operas, especially for the Teatro San Carlo for which he was the official poet. He and Andrea Leone Tottola were the two librettists who dominated theatrical life in Naples in the first quarter of the 19th century. His lyrics were mostly banal and verbose, but were set by the most important composers of the era, such as Giacomo Tritto, Gaetano Andreozzi, Luigi Mosca, Pietro Generali, Saverio Mercadante and Gioachino Rossini. For Rossini alone he wrote texts for Elisabetta, regina d'Inghilterra, Eduardo e Cristina, Armida and Adelaide di Borgogna, which are considered his best works. He also appeared as a character in a scene from the 1991 film Rossini! Rossini! directed by Mario Monicelli.
