Gaufredo (or Geoffrey, or Goffredo) Malaterra (Latin: Gaufridus Malaterra) was an eleventh-century Benedictine monk and historian, possibly of Norman origin. He travelled to the southern Italian peninsula, passing some time in Apulia before entering the monastery of Sant'Agata at Catania, on the isle of Sicily. Malaterra indicates that, prior to his arrival in Catania, he had spent an undefined period away from monastic life, in the worldly service of "Martha".

Jordan is named as son of Count Roger's first marriage in Europäische Stammtafeln but, according to Geoffrey Malaterra, his mother was a concubine of Roger I. Her origin is unknown.
