Gianni di Parigi is an 1839 melodramma comico (opera buffa) in two acts with music by Gaetano Donizetti to a libretto by Felice Romani, which had previously been set by Francesco Morlacchi in 1818 and by Giovanni Antonio Speranza in 1836.
It is derived from Jean de Paris, an 1812 opera by François-Adrien Boïeldieu with a libretto by Claude Godard d'Aucourt de Saint-Just, which had been performed in Naples in 1816.
According to Charles Osborne, the research of Swedish musicologist Anders Wiklund suggests that Donizetti may have begun composing the music for the opera between 1828 and 1830 for a projected performance in Naples which did not occur. It is established with certainty that Donizetti completed the score in 1831, intending it as a vehicle for the popular tenor Giovanni Battista Rubini, who had created the role of Percy in Donizetti's Anna Bolena on 26 December 1830, and to whom Donizetti presented the completed score in 1831. Apparently Rubini did not seriously promote it with opera managements, but somehow it was acquired by Bartolomeo Merelli, who became impresario of La Scala in 1836 and despite the protests of Donizetti produced it there in 1839.
Jeremy Commons, however, points out that Wiklund discovered that in Donizetti's autograph score in the Naples Conservatorio di Musica San Pietro a Majella the overture is clearly dated 1828. Commons notes that the opera's style fits better with florid operas of the 1820s such as Gianni di Calais than with the more romantic 1830s operas such as L'elisir d'amore, and Wiklund suggests that Neapolitan elements in the opera indicate that it was composed in Naples where Donizetti was active in the 1820s. A further score of 1832, with some revisions by the composer (including the omission of the Neapolitan elements), is located in the Casa Ricordi archives in Milan. This may be the score which Donizetti presented to Rubini, who presumably passed it through the hands of Giovanni Ricordi to Merelli.
