Maria of Enghien, also known as Marie of Enghien or d'Enghien (after 1363–1392/1393), was the Lady of Argos and Nauplia in Frankish Greece from 1376 or 1377 to 1388. Because she was a minor when she inherited the lordship from her father, Guy of Enghien, his brother, Louis of Enghien, was appointed to be her guardian. Louis gave Maria in marriage to a Venetian patrician, Pietro Cornaro, in 1377. Maria moved to Venice, but she was involved in the administration of her lordship. After her husband died, she sold the lordship to the Republic of Venice for a regular income in 1388.
