Louise Marie Adelaide Eugènie d'Orléans (August 23, 1777 - December 31, 1847) was the daughter of Louis Philip II, Duke of Orléans and Louise Marie Adélaïde de Bourbon-Penthièvre, and the sister of King Louis-Philippe of France.
In 1814, when her brother Louis-Philippe returned to France to later become King, she returned to live in his household. Now known as Madame Adelaide, she became his loyal advisor (or in 19th century parlance, his "Egeria"). She died two months before the overthrow of Louis-Philippe's reign.
