Francisco de Asís, Duke of Cádiz (Francisco de Asís María Fernando de Borbón; 13 May 1822 – 17 April 1902) was King consort of Spain. He was the husband of Queen Isabella II of Spain from their marriage on 10 October 1846 until Isabella was overthrown on 30 September 1868. Sometimes, his name occurs in its anglicised form as Francis of Assisi. He kept the style and title of king even after her abdication in favour of their son, Alfonso XII. His son was a king regnant, while Francisco himself was a king-father during the reign of the son.
