The Outer Hebrides, often called the Western Isles, make up an island chain off the west coast of Scotland. It is also a parliamentary constituency. The northern island is Lewis and Harris. South of Lewis and Harris is a series of islands, such as South Uist, Benbecula and North Uist. The Outer Herides includes a number of even smaller islands.

The isles form part of the Hebrides, and are separated from the Scottish mainland and from the Inner Hebrides by the stormy waters of the Minch, the Little Minch and the Sea of the Hebrides.

Formerly the dominant language of the Islands, Scottish Gaelic remains spoken even though it has now been largely supplanted by English in some parts.

Sea transport is crucial and a variety of ferry services operate between the islands and to mainland Britain.


The Western Isles became part of the Suðreyjar kingdom of the Norse, who ruled for over 400 years until sovereignty was transferred to Scotland by the Treaty of Perth in 1266. Control of the islands was then held by clan chiefs.

Geology & geography

Most of the islands have a bedrock formed from ancient metamorphic rocks and the climate is mild and oceanic. The Gulf Stream runs nearby. The 15 inhabited islands have a total population of about 26,500 and there are more than 50 substantial uninhabited islands.

Flora and fauna

Much of the archipelago is a protected habitat including both the islands and the surrounding waters. There are 53 Sites of Special Scientific Interest (SSSI) of which the largest are Loch an Duin, North Uist at 15,100 hectares (37,000 acres) and North Harris, which is 12,700 hectares (31,000 acres) in extent.
