Pettigo, also spelt Pettigoe, is a small village and townland 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 County Fermanagh is officially called Tullyhommon but is locally known as 'High Street' because of its hillside position overlooking the remainder of the village.
