Strabane had a population of 13,507 at the 2021 Census. It lies on the east bank of the River Foyle. It is roughly midway from Omagh, Derry and Letterkenny. The River Foyle marks the border between Northern Ireland and the Republic of Ireland. On the other side of the river is the smaller town of Lifford, which is the county town of Donegal. The River Mourne flows through the centre of the town and meets the Finn to form the Foyle River. A large hill named Knockavoe, which marks the beginning of the Sperrin Mountains, forms the backdrop to the town.
