Lisburn City Council was the local authority for an area partly in County Antrim and partly in County Down in Northern Ireland. As of May 2015 it was merged with Castlereagh Borough Council as part of the reform of local government in Northern Ireland to become Lisburn and Castlereagh City Council.
Created in 1974, the council was the second largest in the Belfast Metropolitan Area. Council headquarters were in the city of Lisburn. It was the second-largest council area in Northern Ireland with over 120,000 people and an area of 174 square miles (450Â km) of southwest Antrim and northwest Down. The council area included Glenavy and Dundrod in the north, Dromara and Hillsborough in the south, Moira and Aghalee in the west, and Drumbo in the east.
