Earlstoun Castle, sometimes spelled Earlston Castle, is a derelict tower house near St John's Town of Dalry in Dumfries and Galloway, Scotland. Built in the late sixteenth century, it was home to members of the Gordon family, including William Gordon of Earlston who was killed at the battle of Bothwell Bridge. It is unusual for a tower house of its age for its lack of defensive arrangements: it has no gun loops, its roof is without a parapet or corner turrets, and it lies in open ground without natural defences.
