John Fitzalan, 3rd Lord of Clun and Oswestry (1200–1240[1]) was a Norman nobleman in the Welsh Marches in the county of Shropshire.
John succeeded his brother, William Fitz Alan, 2nd Lord of Oswestry and Clun, who died in 1215 without issue.
[2] He was one of the feudal barons who became a target for the anger of King John of England, whose forces attacked Oswestry town and burned it in 1216.
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 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.
