Clan Morrison is a Scottish clan. The Highland Clan Morrison is traditionally associated with the Isle of Lewis and Harris (Leòdhas) around Ness (Nis), Dun Pabbay, and Barvas (Barabhas), lands in Sutherland around Durness, and in North Uist. There are numerous Scottish clans, both Highland and Lowland, which use the surname Morison or Morrison. In 1965, the Lord Lyon King of Arms decided to recognise one man as chief of all Morrisons, whether their clans were related or not.
