Shapinsay is one of the Orkney Islands off the north coast of mainland Scotland. There is one village on the island, Balfour, from which roll-on/roll-off car ferries sail to Kirkwall on the Orkney Mainland. Balfour Castle, built in the Scottish Baronial style, is one of the island's most prominent features, a reminder of the Balfour family's domination of Shapinsay during the 18th and 19th centuries; the Balfours transformed island life by introducing new agricultural techniques. Other landmarks include a standing stone, an Iron Age broch, a souterrain and a salt-water shower.
With an area of just under 3,000 hectares (7,300 acres), Shapinsay is the eighth largest island in the Orkney archipelago. It is low-lying and fertile, consequently most of the area is given over to farming. Shapinsay has two nature reserves and is notable for its birdlife.
As of the 2001 census, Shapinsay has a population of 300. The economy of the island is based on agriculture and a few small businesses largely related to tourism. Plans for the construction of a wind turbine are under consideration.
