Hugh I of Vermandois (1057 – October 18, 1101), called Magnus or the Great, is a younger son of Henry I of France and Anne of Kiev and younger brother of Philip I.
He is in his own right Count of Vermandois, but an ineffectual leader and soldier, great only in his boasting.
Indeed, Steven Runciman is certain that his nickname Magnus (greater or elder), applied to him by William of Tyre, is a copyist's error, and should be Minus (younger), referring to Hugh as younger brother of the King of France.
