Burray is one of the Orkney Islands in Scotland. It lies to the east of Scapa Flow and is one of a chain of islands linked by the Churchill Barriers. Burray lies between Mainland, Orkney and South Ronaldsay, and is linked to both by the Churchill Barriers. Barriers 1, 2, and 3 connect Burray with Mainland, Orkney via the islets of Glimps Holm and Lamb Holm in Holm Sound to the north east. Barrier 4 links to South Ronaldsay, across Water Sound. To the west is the tidal island of Hunda, also joined by a causeway. Further west, across Scapa Flow, are the islands of Flotta and Calf of Flotta, approximately 6 kilometres (3.7 mi) away.
