Emma of Blois (c. 950 – 27 December 1003) was Duchess of Aquitaine by marriage to William IV, Duke of Aquitaine. She ruled Aquitaine as regent for her son, William V, Duke of Aquitaine, from 996 until 1004.

She was the daughter of Theobald I, Count of Blois and Luitgarde of Vermandois.^[1] In 968, she married William IV, Duke of Aquitaine.^[2] His overindulging in hunting and women offended her greatly. Around 990, he retired to a monastery. During the course of her marriage, she founded the monastery of Saint Peter in Bourgueil^[3] and the abbey of Maillezais.^[4] Emma then ruled Aquitaine as regent for their son William V.
