|Died||1267 (aged 43–44)|
|Resting place||Haughmond Abbey, Shropshire|
|Children||2, including John Fitzalan III|
The son and heir of John Fitzalan, Lord of Oswestry and Clun, from Shropshire. His mother was Isabel, the daughter of William d'Aubigny, 3rd Earl of Arundel by his wife, Mabel of Chester. John obtained possession of his paternal estates on 26 May 1244, aged 21 years.
After the death of his mother's childless brother Hugh d'Aubigny, 5th Earl of Arundel, he inherited jure matris the castle and honour of Arundel in 1243, by which, according to Henry VI's "admission" of 1433, he was later retrospectively held to have become de jure Earl of Arundel. He was never styled as such during his lifetime, however.
In 1257 the Welsh Lord Gruffydd ap Gwenwynwyn, in the southern realm of the Kingdom of Powys, sought the aid of the Lord of Oswestry against Llywelyn ap Gruffudd. John Fitzalan was a surviving member of the English force that was defeated at the hands of the Welsh at Cymerau in Carmarthenshire.
By 1278 to 1282 his sons were engaged in Welsh border hostilities, attacking the lands of Llywelyn.
He is buried at Haughmond Abbey in Shropshire.
