The Chief Baron of the Irish Exchequer was the Baron (judge) who presided over the Court of Exchequer (Ireland). The Irish Court of Exchequer was a mirror of the equivalent court in England and was one of the four courts which sat in the building which is still called The Four Courts in Dublin. The last Chief Baron, The Rt Hon. Christopher Palles, continued to hold the title after the Court was merged into a new High Court of Justice in Ireland in 1878, until his retirement in 1916, when the office lapsed.
