Princess Marie-Hélène Angela “Marilène” of Orange-Nassau, van Vollenhoven-van den Broek (née: van den Broek, born 4 February 1970) is the wife of Prince Maurits of Orange-Nassau, van Vollenhoven, and was thereby member of the Dutch Royal House until King Willem-Alexander’s accession in 2013 rendered Prince Maurits too distantly related to the reigning monarch. She remains a member of the larger Dutch Royal Family.

Princess Marilène was born in Dieren, Rheden, and is the youngest daughter of Hans van den Broek and Josee van den Broek-van Schendel. Marilène van den Broek obtained her highschool diploma (pre-university secondary education) in Wassenaar in 1988. She studied from 1988 to 1994 at the University of Groningen where she received her MSc degree in Business Administration. Princess Marilène currently works at the Rijksmuseum Amsterdam, a Dutch national museum dedicated to arts, crafts, and history.
