Loch Dochart is a small freshwater loch on the Lochdochart Estate in Stirling, Scottish Highlands. It lies approximately 1.7 km (1.1 mi) to the east of the town of Crianlarich at the foot of Ben More. There is a small wooded island in the middle of the loch on which stands the ruins of a castle originally built by Sir Duncan Campbell between 1583 and 1631.
