Saint Aye was a Frankish Benedictine abbess who lived in the region of Mons during the late seventh and early eighth centuries. Born into nobility as the daughter of Count Brunulphe I, she was a relative of Saint Waldetrudis. After marrying Saint Hidulf of Hainault, she eventually left her marriage to pursue a religious vocation. She dedicated her life to the Abbey of Mons, where she served as an abbess and donated her personal property to the community of nuns.
