Norroy and Ulster King of Arms is the provincial King of Arms at the College of Arms with jurisdiction over England north of the Trent and Northern Ireland. The two offices of Norroy and Ulster were formerly separate. Norroy King of Arms is the older office, there being a reference as early as 1276 to a "King of Heralds beyond the Trent in the North". The name Norroy is derived from the Old French nort roy meaning 'north king'. The office of Ulster Principal King of Arms for All-Ireland was established in 1552 by King Edward VI to replace the older post of Ireland King of Arms, which had lapsed in 1487.
Ulster King of Arms was not part of the College of Arms and did not fall under the jurisdiction of the Earl Marshal, being the heraldic authority for the Kingdom of Ireland (the jurisdiction of the College of Arms being the Kingdom of England and Lord Lyon's Office that of the Kingdom of Scotland).
