John FitzAlan, 13th Earl of Arundel

John FitzAlan, 13th Earl of Arundel, 3rd Baron Maltravers (1 August 1385 – 21 April 1421) was an English nobleman.

FitzAlan was the son of John FitzAlan, 2nd Baron Arundel, and Elizabeth le Despenser, and became Baron Arundel on his father's death in 1390 and Baron Maltravers on his grandmother's death in 1405. In 1415 his cousin Thomas FitzAlan, 12th Earl of Arundel died, leaving FitzAlan as his closest male heir. The Earldom of Arundel had been entailed to heirs male, and so the next year FitzAlan was summoned to parliament as Earl of Arundel.

However the inheritance was challenged by Thomas Mowbray, 1st Duke of Norfolk, who was married to the late Earl's eldest sister. The dispute was not settled during their lifetimes, and FitzAlan was subsequently summoned to Parliament as Baron Maltravers, not Earl of Arundel.

FitzAlan married Eleanor (died 1 August 1455), daughter of Sir John Berkeley (1349–1428) of Beverstone, Gloucestershire and Elizabeth Bettershorne, with whom he had two sons:

• John FitzAlan, 14th Earl of Arundel, who eventually succeeded in his claim to the earldom.
• William FitzAlan, 16th Earl of Arundel, married Joan Neville, daughter of Richard Neville, 5th Earl of Salisbury.

After his death his widow married successively Sir Richard Poynings (died 10 June 1429), and Lord Hungerford (died 9 August 1449).
