John Fitzalan, Lord of Oswestry (1200–1241) was Lord of Clun and Oswestry, in the Welsh Marches, now within the modern day English county of Shropshire.
He was one of the barons who became a target for the anger of King John of England, whose forces attacked Oswestry town and burned it in 1216. John Fitzalan was close to Llywelyn ap Iorwerth until 1217.
He was also a representative of the Crown in a dispute between King Henry III of England and the Welsh leader, Llywelyn the Great in 1226. In the same year he mediated between a neighbour, William Pantulf, Lord of Wem in Salop and Madog ap Gruffydd (died 1236), Lord of Powys and a cousin to Llywelyn ap Iorwerth.
In 1233/4 during the conflict between King Henry III, the Earl Marshal and Llywelyn the Great, John Fitzalan sided firmly with the Crown and Oswestry was again attacked, this time by Welsh forces.
