Maria Maddalena Morelli Fernandez (17 March 1727, Pistoia – 8 November 1800, Florence), also known by the Arcadian pseudonym Corilla Olimpica, was a Florentine Italian poetess, improvisatrice, and musician. The official poetess to the grand ducal court in Florence (1765–75), she won fame as the foremost female performer of the improvised poetry then popular in Italy, and was controversially crowned with the laurel wreath on the Roman Capitol in 1776, an event later fictionalised by Madame de Staël in Corinne.
