2023 Newry, Mourne and Down District Council election

The 2023 election to Newry, Mourne and Down District Council was held on 18 May 2023, alongside other local elections in Northern Ireland, two weeks after local elections in England. The Northern Ireland elections were delayed by 2 weeks to avoid overlapping with the coronation of King Charles III.

41 members were returned to the council via Single Transferable Vote.
