Prince Hugo de Bourbon de Parme (Carlos Hugo Roderik Sybren; born 20 January 1997), formerly Hugo Klynstra, is a member of the extended Dutch royal family as the son of Prince Carlos, Duke of Parma. He was the first great-grandchild of Queen Juliana of the Netherlands. Born out of wedlock, he was denied titles and family rights by his father until the Dutch Council of State ruled in his favor in 2018, granting him the style and title of His Royal Highness Prince Carlos Hugo Roderik Sybren de Bourbon de Parme. Despite the ruling, he is neither a member of the Dutch royal house (although considered a member of the extended Dutch royal family) nor a member of the House of Bourbon-Parma and is not in the line of succession to the defunct Parmese throne nor the Carlist line of succession to the Spanish throne.
