Sir James Alleyn

Sir James Alleyn (died c. 1457) was an Irish judge of the fifteenth century. He held the offices of Speaker of the Irish Privy Council, Chief Justice of the Common Pleas for Ireland and Lord Chief Justice of Ireland. he later owned lands in that county. He became a justice of the liberty of Ulster in 1425, and was knighted in the same year.

Some of these "wrongs" were personal grievances, as Fortescue and Alleyn complained of the insults and assaults they had suffered in connection with the mission itself, including a claim that they had been physically assaulted.

In 1444, he was Speaker of the Great Council held at Drogheda, which was mainly concerned with ending the Butler-Talbot feud, which had bedevilled Irish public life for decades.

He died or retired in 1457.
