Auchencloigh Castle or Auchincloigh Castle (NGR NS 4945 1666 ) is a ruined fortification near the Burnton Burn, lying within the feudal lands of the Craufurd Clan, situated in the Parish of Ochiltree, East Ayrshire, Scotland. No description or accurate pictorial representation of Auchencloigh castle seems to have survived. The site of the castle is on a mound and in 1978 some of its walls were standing at a height of between 0.6 and 1.6m and several feet in thick in a few places. The walls formed a rectangle and the interior seems to have been subdivided into several small rooms.
