John Fitzalan, 6th Earl of Arundel

John Fitzalan, 6th Earl of Arundel, 3rd Baron Maltravers (1 August 1385 – 21 April 1421) was an English nobleman.

He was with the army in Scotland in 1383 and with the English Fleet on the western coast of France.

However, the inheritance, insofar as it related to the property of the prior earl rather than the title and Arundel Castle, was challenged and disputed between Arundel and the previous earl's sisters.

The dispute was not settled during their lifetimes, and John Fitzalan was subsequently summoned to Parliament as Baron Maltravers, not as Earl of Arundel.

He married Eleanor Berkeley (died 1 August 1455), a daughter of Sir John Berkeley (1352–1428) of Beverstone Castle in Gloucestershire by his wife Elizabeth Betteshorne.
