Slieve Gullion (from Irish Sliabh gCuillinn, meaning 'hill of the steep slope' or Sliabh Cuilinn, "Culann's mountain") is a mountain in the south of County Armagh, Northern Ireland. The mountain is the heart of the Ring of Gullion and is the highest point in the county, with an elevation of 573 metres (1,880 ft). At the summit is a small lake and two ancient burial cairns, one of which is the highest surviving passage grave in Ireland. Slieve Gullion appears in Irish mythology, where it is associated with the Cailleach and the heroes Fionn mac Cumhaill and Cú Chulainn. It dominates the countryside around it, offering views as far away as County Antrim, Dublin Bay and County Wicklow on a clear day. Slieve Gullion Forest Park is on its eastern slope.
Villages around Slieve Gullion include Meigh, Drumintee, Forkhill, Mullaghbawn and Lislea. The mountain gives its name to the surrounding countryside, and is the name of an electoral area within Newry, Mourne and Down District Council.
