The Abbey of Sainte-Marie-des-Dames (French: Abbaye aux Dames de Saintes) was the first Benedictine abbey for women in Saintes in Charente-Maritime in France. It was founded in 1047 by Geoffrey II, Count of Anjou. One of its abbesses was Agnès de Barbezieux (1134-1174), whose relative, Eleanor of Aquitaine, was a generous donor to the abbey.
Madame de Montespan was educated here.
It is located next to the town's Arch of Germanicus and was classified a monument historique in 1948.
