Lecale is a peninsula in the east of County Down, Northern Ireland. It lies between Strangford Lough and Dundrum Bay. In the Middle Ages it was a district or túath in the Gaelic Irish kingdom of Ulaid, then became a county in the Anglo-Norman Earldom of Ulster. Later it became a barony, which was split into Lecale Lower and Lecale Upper by 1851. Its largest settlement is the town of Downpatrick. Other settlements include Ardglass, Killough and Strangford. The peninsula has a high concentration of tower houses. Much of it is part of the 'Strangford and Lecale' Area of Outstanding Natural Beauty.
