Blair Castle stands in its grounds near the village of Blair Atholl in Perthshire in Scotland. It is the ancestral home of the Clan Murray, and was historically the seat of their chief, the Duke of Atholl, though the current (12th) Duke, Bruce Murray, lives in South Africa. The castle stands in Glen Garry, and commands a strategic position on the main route through the central Scottish Highlands.

Blair Atholl is a village in Perthshire, Scotland, built about the confluence of the Rivers Tilt and Garry in one of the few areas of flat land in the midst of the Grampian Mountains. The Gaelic place-name Blair, from blàr, 'field, plain', refers to this location. Atholl, which means 'new Ireland', from the archaic Ath Fhodla is the name of the surrounding district.
