Scotasay (Gaelic; Scottish Gaelic: Sgeotasaigh) is small island in the Outer Hebrides of Scotland. It lies 11NaN1 off the east coast of Harris and gives some shelter to the ferry port of Tarbert. There are two houses on the island, a wind turbine and a fresh water tank.[1]
The island had 15-20 inhabitants in the early 20th century but there are no records of any permanent inhabitation since then.
