Jeanne Quinault (born and baptized 13 October 1699 in Strasbourg, died 18 January 1783 in Paris), was a French actress, playwright and salon hostess.
She was usually called Mlle Quinault la cadette (the younger), to distinguish her from her older sister, Marie-Anne-Catherine Quinault, also an actress.
She herself thought her name was Jeanne-Françoise Quinault until 1726, when she obtained a copy of her baptismal record and discovered her legal name, but most references to her use the two given names.
