The Doune of Invernochty is a 12th-century castle in Scotland, of which only earthworks survive. The Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) note that it is "one of the finest examples of Norman earthwork castles in Scotland, and appears to be the sole Scottish example of a motte with Norman stonework on its summit." It is located in Strathdon, Aberdeenshire, at the confluence of the River Don and the Water of Nochty. It stands between the villages of Bellabeg and Strathdon; the latter used to be called Invernochty. Doune of Invernochty is a scheduled monument.
