Pettigo (also spelt Pettigoe; Irish: Paiteagó) is a small village on the border of County Donegal, Republic of Ireland and County Fermanagh, Northern Ireland. It is bisected by the Termon River which is part of the border between the Republic of Ireland and Northern Ireland. The portion of the village in Northern Ireland is officially called Tullyhommon, but is locally known as 'High Street' due to its hillside position overlooking the remainder of the village. The rest of the village in the Republic includes Main Street, Mill Street and Station Street, all of which meet in The Diamond at the centre of the village. There are also two relatively modern housing estates on the northern outskirts, namely Termon Villas and St. Patrick's Terrace along with new developments such as Mill Grove.
