Clan Cairns is a Scottish clan. The clan does not have a chief recognised by the Lord Lyon King of Arms, therefore the clan has no standing under Scots Law. Clan Cairns is considered an armigerous clan, meaning that it is considered to have had at one time a chief who possessed the chiefly arms, however no one at present is in possession of such arms. The arms of Cairns of that Ilk are blazoned as: Gules, three martlets Or.
