William d'Aubigny, 3rd Earl of Arundel (before 1180 – 1 February 1221) was an English nobleman, a favourite of King John, and a participant in the Fifth Crusade.
William was son of William d'Aubigny, 2nd Earl of Arundel and Matilda de St Hilary, and grandson of Queen Adeliza of Leuven.
William was a favourite of King John. He witnessed King John's concession of the kingdom to the Pope on 15 May 1213. On 14 June 1216 he joined Prince Louis (later Louis VIII of France) after King John abandoned Winchester. He returned to the allegiance of the King Henry III after the Royalist victory at Lincoln, on 14 July 1217.
He joined in the Fifth Crusade (1217–1221), in 1218. He died on his journey home, in Caneill, Italy, near Rome, on 1 February 1221. News of his death reached England on 30 March 1221. He was brought home and buried at Wymondham Abbey.
His title was held by his son William, until he died, childless, in 1224, when it was passed to William's youngest son Hugh.
After 1196 and before 1200 William married Mabel of Chester (born c. 1173), daughter of Hugh de Kevelioc, 5th Earl of Chester, and Bertrade de Montfort. They were the parents of eight children.
