Stranorlar ("valley of the floor" or flat bottomed valley) is a small town in the Finn Valley of County Donegal, in Ireland. Stranorlar and Ballybofey (located on the other side of the River Finn) form the Twin Towns.

Drumboe Woods are the major attraction of Stranorlar. The woods are managed by Coillte and provide walking routes along the banks of the River Finn and the upper woods. Outside the town, a small folly called The Steeple is a popular destination for many walkers. From the top of the tower, on a clear day, the hillfort of The Grianan of Aileach can be seen. There is a raised ring fort at Dunwiley, outside the town. There are numerous guest houses throughout the town and on the main street is Stranorlar's only hotel. Kee's Hotel is a family-run hotel, first established in the 19th century as a coach house. The vernacular architecture of the town is largely 19th century solid two and three-storey townhouses, one or two of some interest. Unfortunately, they are rapidly being lost to development.
