Lifford is the county town of County Donegal, Ireland. It is the administrative capital of the county and the seat of Donegal County Council, although the town of Letterkenny is often mistaken for fulfilling this role.
Lifford lies in the Finn Valley area of East Donegal where the River Finn meets the River Mourne to create the River Foyle.
The town grew up around a castle built there by Manghus Ó Domhnaill, ruler of Tír Chonaill (mostly modern County Donegal), in the 16th century. It later became a British Army garrison town until most of Ireland won independence as a dominion in 1922.
It lies across the River Foyle from Strabane (in County Tyrone, Northern Ireland) and is linked to that town by Lifford Bridge. Lifford has achieved national recognition in the 2008 Tidy Towns Awards.
For centuries, Lifford has been the Gateway to Donegal.
