ADHEMAR (ADEMAR, AIMAR, AELARZ) DE MONTEIL (died 1098), crusader, was bishop of Puy en Velay from before 1087, and accompanied Raymond IV., count of Toulouse, to the East as apostolic legate. He negotiated with Alexis Comnenus at Constantinople, re-established at Nicaea some discipline among the crusaders, caused the siege of Antioch to be raised, and died in that city of the plague.
