Adelaide di Guesclino is an opera (dramma di sentimento) in two acts composed by Simon Mayr. The Italian libretto by Gaetano Rossi is based on Voltaire's 1734 play Adélaïde du Guesclin. The opera premiered at La Fenice in Venice on 1 May 1799 with Caterina Angiolini in the title role.
Adelaide di Guesclino premiered on 1 May 1799 at La Fenice in a production designed by Nicola Pellandi and was coupled with the premiere of Giuseppe Antonio Capuzzi's ballet Clotilde. It was Mayr's fifth opera to premiere at La Fenice. Voltaire's play Adélaïde du Guesclin, on which Gaetano Rossi based the libretto, was Voltaire's first play to use French historical characters as protagonists, although the actual plot was entirely of his own invention. He wrote in a letter some months before the play's premiere, "I have packed in as much I could of love, jealousy, fury, propriety, probity, and grandeur of soul."
Although forgotten now, Mayr's operatic version was very successful in its day. In the years following its premiere it was performed in several Italian cities, including Verona, Modena, Pisa, and Sienna (sometimes titled Carlo duca di Vandomo o sia L'Adelaide or simply Adelaide). The 1808 performance in Siena marked the stage debut of the tenor Giovanni David, whose father and teacher Giacomo David was also in the cast. Outside of Italy, the opera was performed in the original Italian in Vienna and Prague in 1802, in Dresden in 1807, and in Amsterdam in 1817. It was also performed in German as Adelheid von Guesclin in several German cities between 1804 and 1819.
