Jeanne Quinault (baptized 13 October 1699 – 18 January 1783) 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.
