Donaghadee ward encompasses the coastal town of Donaghadee and its immediate rural surroundings in the east of the Ards and North Down Borough. The area is defined by its working harbour, which remains active with fishing vessels and is the point of departure for regular passenger ferries to the Copeland Islands. The town's layout radiates from this central port, with residential streets climbing gently uphill from the seafront.
A prominent local landmark is the white-painted lighthouse on the harbour's east pier, a structure guiding maritime traffic for over two centuries. The coastline features rocky shores and the protected anchorage of Millisle Bay to the south. Inland, the ward includes farmland and the settlements of Ballyvester and Ballyfrench, contributing to its mixed character of maritime activity and agricultural land use.
