Princess Belle-Etoile is a French literary fairy tale written by Madame d'Aulnoy. Her source for the tale was Ancilotto, King of Provino, by Giovanni Francesco Straparola.

Marie-Catherine Le Jumel de Barneville, Baroness d'Aulnoy, also known as Countess d'Aulnoy, was a French author known for her literary fairy tales. The term contes de fées has been attributed to her, but her work was called "contes DES fées" ; the term "contes DE fées" comes from Mme de Murat's first fairytale compilation: "Contes de fées", published in 1698.
