North Down Borough Council was a Local Council in County Down in Northern Ireland. It merged with Ards Borough Council in May 2015 under local government reorganisation in Northern Ireland to become North Down and Ards District Council.
Its main town was Bangor, 12 miles east of Belfast with a population of approximately 68,000. The council was headquartered in Bangor. Its secondary centre was the former Urban District of Holywood, 8 km northeast of Belfast with a population of approximately 10,000. Most of the remainder of a total population was in suburban villages along the southern shore of Belfast Lough. The area of the former Borough is heavily suburbanised, railway links with Belfast are good and the area has been the domain of Belfast commuters since the mid-19th century. The former Borough is often held to be the wealthiest area in Northern Ireland, although there are pockets of deprivation in a string of overspill public housing estates along the Bangor Ring Road.
