Tandragee ward covers a largely rural portion of southeastern Armagh City, Banbridge and Craigavon. The area is characterised by rolling drumlin hills and farmland, with the River Cusher flowing through its landscape. The settlement of Tandragee itself acts as the main service centre for the surrounding townlands. Economic activity has traditionally been linked to agriculture and local industry.
The ward is dominated by the presence of Tandragee Castle, a 19th-century manor house set within extensive grounds. This estate overlooks the town and adds a distinct historical character to the area. The local geography influences a pattern of dispersed dwellings and smaller villages. Road connections primarily follow the natural contours of the land between the larger population centres to the north and west.
