Torthorwald is a village and civil parish in Dumfries and Galloway, south-west Scotland. It is located 6 kilometres (3.7 mi) east of Dumfries on the A709 road to Lochmaben. The area was the property of the de Torthorwald family until the end of the 13th century, when the estate passed by marriage to the Kirkpatricks. In 1418, William de Carleil married the Kirkpatrick heiress. He may have been the builder of Torthorwald Castle, which was erected around this time, possibly on top of an earlier a motte.
