Tarbert Castle is located on the southern shore of East Loch Tarbert, at Tarbert, Argyll, Scotland, at the north end of Kintyre. Tarbert Castle was a strategic royal stronghold during the Middle Ages and one of three castles at Tarbert. The castle overlooks the harbour and although pre 14th century in construction, the tower dates back to 1494.
A towerhouse was added in the 16th century, which is the most noticeable part of the remains. The castle occupies high land above the village, providing views up Loch Fyne and beyond to the Firth of Clyde.
