Yolanda of Vianden was a 13th-century Dominican nun and prioress who lived in Luxembourg. Born into nobility as the daughter of Count Henry I of Vianden, she famously chose a religious life despite her parents' desire to arrange a noble marriage for her. After initially fleeing to the Marienthal monastery as a novice, she eventually overcame parental opposition to dedicate herself to prayer and charity. She served as the prioress of the community from 1258 until her death in 1283, becoming a significant figure in local religious history.
