Vacsay (Scottish Gaelic: Bhacsaigh from Old Norse "bakkiey" meaning "peat bank island") is one of the Outer Hebrides. It is off the west coast of Lewis in West Loch Roag. It is 41 hectares (0.16 sq mi) in size, and 34 metres (112 feet) at its highest point.
Like many of the surrounding islands, Vacsay is uninhabited due to the Highland Clearances, which occurred here in 1827.
It was bought in 1993 by Sirdar Baron Iqbal Singh, a London business man, who currently lives in Lesmahagow. He has bought the title, "Lord of Butley Manor" and also wishes to rename Vacsay, "Robert Burns' island" or Eilean Burns, although Burns never visited the Outer Hebrides.
