John FitzAlan, 13th Earl of Arundel (1385–1421) was an English nobleman. He 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.
John FitzAlan, 2nd Baron Arundel, also called John de Arundel (30 November 1364 – 14 August 1390), of Buckland, Surrey, was the son of John FitzAlan, 1st Baron Arundel and Eleanor Maltravers. John was with the army in Scotland in 1383 and with the English Fleet in the western coast of France. He married Elizabeth le Despenser, daughter of Edward le Despencer, 1st Baron le Despencer (Despenser), by Elizabeth Burghersh, daughter and heiress of Bartholomew de Burghersh, 2nd Baron Burghersh.
The title of Baron Arundel was created in the Peerage of England on August 4, 1377 by the summons of John Fitzalan to Parliament as "Johanni de Arundell". As he was then married to Eleanor Maltravers, coheir and eventual sole heir of John Maltravers, 1st Baron Maltravers, this is sometimes taken to be identical with the Barony of Maltravers. The barony subsequently came to be held by the Earl of Arundel, now itself a subsidiary title of the Duke of Norfolk.
