Killultagh is one of the seven district electoral areas (DEA) in Lisburn and Castlereagh, Northern Ireland. The district elects five members to Lisburn and Castlereagh City Council and contains the wards of Ballinderry, Glenavy, Maghaberry, Stonyford and White Mountain. Killultagh forms part of the Lagan Valley constituencies for the Northern Ireland Assembly and UK Parliament, and part of the South Antrim constituencies for the Northern Ireland Assembly and UK Parliament.
It was created for the 1985 local elections, replacing Lisburn Area A and part of Lisburn Area C which had existed since 1973, where it originally contained seven wards (Ballymacash, Ballymacoss, Glenavy, Knockmore, Lisnagarvy, Magheragall and Moira). For the 1993 local elections it was reduced to five wards, losing Ballymacash, Ballymacoss and Lisnagavy to the new Lisburn North DEA, and gaining Ballinderry and Maghaberry. For the 2014 local elections, Moira moved to the new Downshire West DEA, and Knockmore moved to Lisburn South DEA, while Killultagh gained Stonyford and White Mountain.
