Massimilla Doni is a short story by Honoré de Balzac. Its first chapter was published in 1837 in the Études philosophiques of la Comédie humaine alongside Gambara, les Proscrits and Séraphîta. Its second chapter was published in 1839 in the review la France musicale, under the title Une représentation du 'Mosè in Egitto' by Rossini in Venice, with a preamble underlining the role Stendhal had played in making Rossini known in France. George Sand, with whom Balzac had shared his enthusiasm for Mosè in Egitto, advised the writer to put his story on paper.
