The Constituency Commission (Irish: An Coimisiún um Thoghlaigh) is an independent commission in Ireland which had advised on redrawing of constituency boundaries of Dáil constituencies for the election of members to Dáil Éireann (the house of representatives of the Oireachtas) and European Parliament constituencies prior to the establishment of the Electoral Commission in 2023. Each commission was established by the Minister for Housing, Planning and Local Government after the census. The Commission then submitted a non-binding report to the Oireachtas, and was dissolved. A separate but similar Local Electoral Area Boundary Committee fulfilled the same function for local electoral area boundaries of local government areas.
