Moffat (Scottish Gaelic: Am Magh Fada, "The Long Plain") is a former burgh and spa town in Dumfries and Galloway, Scotland, lying on the River Annan, with a population of around 2,500. It was a centre of the wool trade and a spa town. The Moffat House Hotel, located at the northern end of the High Street, was designed by John Adam. The nearby Star Hotel, a mere 20 ft (6 m) wide, boasted a record in the Guinness Book of Records as the narrowest hotel in the world.
