The Chancellor of the Exchequer of Ireland was the head of the Exchequer of Ireland and a member of the Dublin Castle administration under the Lord Lieutenant of Ireland in the Kingdom of Ireland. In early times the title was sometimes given as Chancellor of the Green Wax. In the early centuries, the Chancellor was often a highly educated cleric with knowledge of Finance. In later centuries, when sessions of Parliament had become regular, the Chancellor was invariably an MP in the Irish House of Commons.
