The name "Kingussie" originates from the Gaelic, "Ceann a' Ghiuthsaich" which indicates "Head of the Pine woodland". The ruins of the early 18th-century Ruthven Barracks (Historic Scotland; open to visitors whatsoever times) lie near the initial site of the village, which was moved to stay clear of the flood plain of the River Spey. The Hanoverian Barracks were built on the site of Ruthven Castle, the seat of the Comyns, Lords of Badenoch in the Middle Ages.
