Princess Françoise of Orléans (Françoise Isabelle Louise Marie; 25 December 1902, Paris – 25 February 1953, Paris) was born a Princess of Orléans and was a Princess of Greece and Denmark by marriage. She was thus a member of the Greek royal family. She was a descendent of Louis-Philippe of France.
This royal marriage was unusual in that era, a Catholic marrying a non-Catholic (he was Greek Orthodox, whilst she was Roman Catholic). They had only one child, the writer Prince Michael of Greece and Denmark (born 1939), who married the Greek artist Marina Karella (born 1940) - that marriage did not conform to the laws of the royal house and thus deprived him of all right of succession to the Greek throne.
