The Bar of Northern Ireland is the professional association of barristers for Northern Ireland, with over 600 members. It is based in the Bar Library, beside the Royal Courts of Justice in Belfast, together with the Bar Council of Northern Ireland and the Executive Council. The Executive Council has taken on many of the functions formerly exercised by the Benchers of the Inn of Court of Northern Ireland, which was established at a meeting of the Bench and Bar held on 11 January 1926.

The Honorable Society of King's Inns is the "Inn of Court" for the Bar of Ireland. Established in 1541, King's Inns is Ireland's oldest school of law and one of Ireland's significant historical environments.
