Vacsay (Scottish Gaelic: Bhacsaigh from Old Norse "bakkiey" meaning "peat bank island") is one of the Outer Hebrides.

It is 41 hectares (0.16 square miles) 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.

[3] It was bought in 1993 by Sirdar Baron Iqbal Singh, a London business man, who currently lives in Lesmahagow.

[3] Vacsay has an extremely complicated coastline, and is connected at low tide to several surrounding islets such as Trathasam, and Liacam.
