William Clito (25 October 1102 – 28 July 1128), was the fourteenth Count of Flanders and titular Duke of Normandy. His surname "Clito" was a Latin term equivalent to the Anglo-Saxon "Aetheling", and the Germanic "Adelinus" (used to refer to his first cousin, William Adelin, the son of Henry I). Both "Clito" and "Atheling" signified "man of royal blood", or the modern equivalent, "prince".
