Princess Marie, born as Marie Agathe Odile in Paris in 1976, is the second wife of Prince Joachim of Denmark. She converted to the Evangelical Lutheran Church upon marrying into the Danish royal family and became a Danish citizen. The Princess is the mother of two children, Count Henrik and Countess Athena, along with the stepmother to Prince Joachim's two sons from his previous marriage.

Princess Marie is the sole child of her parents, Alain Cavallier and Françoise Grassiot. After her parents' divorce, she gained four half-brothers. From her mother's subsequent marriage, she has two half-brothers, Benjamin and Gregory Grandet. From her father's side, she has two more half-brothers, Charles and Edouard Cavallier. These half-brothers were raised mainly in Paris, with Princess Marie remembering her older brothers as protective during her childhood.

The Princess pursued her education in Europe and the United States, studying economics and international business at institutions such as Marymount Manhattan College and Babson College. Before marrying Prince Joachim in 2008, she worked in public relations and marketing in various capacities, including roles with Estée Lauder, DoubleClick Inc., and the French agency Media Marketing.

Upon marrying Prince Joachim, Princess Marie has taken on official duties, supported numerous cultural and social causes, and completed emergency-services training with the Danish Emergency Management Agency.
