Dryhope Tower is a ruined Scottish peel tower in the valley of the Yarrow Water, in the historic county of Selkirkshire, now part of the Scottish Borders. It lies approximately equidistant between the burghs of Moffat and Selkirk, and defended the north eastern end of St Mary's Loch. The site itself was protected on two sides, to the east by the Dryhope Burn and to the west by the Kirkstead Burn.
