Baile na Finne (English name: Fintown) is a small village and townland on the banks of Lough Finn in County Donegal, Ireland. It is within the Gaeltacht, an Irish-speaking area, in the west of the county. Overlooked by Aghla (589m, 1961 ft) and Screig Mountains, its main attraction is an Mhuc Dhubh, the Fintown Railway (Donegal's only operational narrow gauge railway), which runs along the length of Lough Finn. The village was named after a mythological woman, Finngeal, who drowned in the lake after attempting to save her wounded brother Thor.
