Hortense Félicité de Mailly-Nesle, Mademoiselle de Chalon, marquise de Flavacourt was a French courtier, one of the five famous de Nesle sisters, four of whom would become the mistress of King Louis XV. Unlike each of her four sisters, she never became the king's mistress, though she was often the subject of speculations.
