Arnoul d'Audrehem (c. 1305 – 1370) was a French soldier. He was born at Audrehem, in the present arrondissement of Saint-Omer, in the département of Pas de Calais. Nothing is known of his career before 1332, when he is heard of at the court of Philip VI of France. Between 1332 and 1342 he went three times to Scotland to aid King David Bruce in his wars. In 1342 he became captain for the king of France in Brittany; then he seems to have served in the household of the duke of Normandy, and in 1346, as one of the defenders of Calais, was taken as a prisoner to England by Edward III.
