The Bar of Ireland is the professional association of barristers for Ireland, with over 2,000 members. It is based in the Law Library, with premises in Dublin and Cork. It is governed by the General Council of the Bar of Ireland, commonly called the Bar Council of Ireland, which was established in 1897. The Council is composed of twenty-five members: twenty who are elected, four co-opted, and the Attorney-General, who holds office ex officio. Every year, ten members are elected for two-year terms; five by senior counsel and five by junior counsel.

A barrister is a type of lawyer in common law jurisdictions. Barristers mostly specialise in courtroom advocacy and litigation. Their tasks include arguing cases in courts and tribunals, drafting legal pleadings, researching the law and giving legal opinions.
