Armagh City and District Council was a district council in County Armagh in Northern Ireland. It merged with Banbridge District Council and Craigavon Borough Council in May 2015 under local government reorganisation in Northern Ireland to become Armagh, Banbridge and Craigavon District Council. The proposed reforms were postponed in 2010, and the most recent district council elections took place in 2011. Together with part of the district of Newry and Mourne, it formed the Newry & Armagh constituency for elections to the Westminster Parliament and Northern Ireland Assembly.
