The leader of the opposition in Ireland is a de facto term sometimes used to describe the politician who leads the largest party in the parliamentary opposition in Dáil Éireann, the house of representatives of the Oireachtas. In the Dáil, the leader of the opposition sits on the right-hand side of the Ceann Comhairle and directly opposite the Taoiseach. The role is not an official one and is not recognised in the Irish constitution, nor in legislation.
