TheOuter Hebrides is a chain of more than 100 islands and smallskerries located about 70 kilometres (43 mi) west of mainlandScotland. There are 15 inhabited islands in thisarchipelago, which is also known as the Western Isles and archaically as the Long Isle (Scottish Gaelic:An t-Eilean Fada).[Note 1]
Lewis and Harris is the largest island in Scotland and the third largest in theBritish Isles, after Great Britain and Ireland.[2] It incorporatesLewis in the north andHarris in the south, both of which are frequently referred to as individual islands, although they are joined by a land border.[Note 2] The largest settlement in Lewis and in the Outer Hebrides isStornoway.
To the south across the Sound of Harris lie the Uists andBenbecula, which were joined by a series of causeways constructed between 1940 and 1960 to improve transport links.[4] Further south areBarra and the smallerBarra Isles, whose southernmost extremity isBarra Head. There are other outliers with cultural links to the Outer Hebrides that are not part of the archipelago itself. These include theSt Kilda group, which are quite distinct geologically and no longer inhabited,[5]Sula Sgeir andNorth Rona to the north and isolatedRockall, which is 367 kilometres (228 mi) to the west ofNorth Uist.[Note 3]
The islands of Scotland's west coast are known collectively as the Hebrides and theOuter Hebrides are separated from theInner Hebrides byThe Minch to the north and theSea of the Hebrides to the south. The Outer Hebrides are administered byComhairle nan Eilean Siar and had a population of 26,140 in 2022.[7] The Outer Hebrides have historically been a strongScottish Gaelic (Gàidhlig) speaking area. Despite recent declines, in the 2001 census more than 50% of the resident population in each island was able to speak Gaelic, for an overall total of 15,842 speakers throughout the archipelago.[8] The modern economy centres on tourism,crofting, fishing, and weaving, the latter of which includes the manufacture ofHarris tweed. The archipelago is exposed to wind and tide, and there are numerouslighthouses as an aid to navigation.[9]
The definition of an island used in this list is that it is "land that is surrounded by seawater on a daily basis, but not necessarily at all stages of the tide, excluding human devices such as bridges and causeways".[Note 4]





The inhabited islands of the Outer Hebrides had a total population of 26,502 in 2001,[10] 27,684 at the time of the2011 census[11] and was 26,140 in 2022.[7]
The highest peaks of the islands have names deriving from both Gaelic andOld Norse indicating the historical importance of these two cultures. The archeological record for the period of Viking domination during theEarly Historic period is however very limited, theLewis chessmen being an exception.
In addition to the North Ford (Oitir Mhòr) and South Ford causeways that connect North and South Uist, Benbecula and the northern of the twoGrimsays in the southern part of the island chain, several other islands are now connected by causeways and bridges.Great Bernera andScalpay have bridge connections to Lewis and Harris respectively,Baleshare andBerneray are linked to North Uist,Eriskay to South Uist,Flodaigh,Seana Bhaile and the southernGrimsay to Benbecula, andVatersay is connected to Barra by theVatersay Causeway.[4][12][13] This means that all of the inhabited islands are now connected to at least one other island by a land transport route.

This is a list of islands with an area greater than 25 hectares (approximately 37 acres). Records for the last date of settlement for the smaller uninhabited islands are incomplete, but most of the islands listed here would have been inhabited at some point during theNeolithic, Iron Age,Early Historic orNorse periods.
In common with the other main island chains of Scotland many of the more remote islands were abandoned during the 19th and 20th centuries, in some cases after continuous habitation since the prehistoric period. This process involved a transition from these places being perceived as relatively self-sufficient agricultural economies[20] to a view becoming held by both island residents and outsiders alike that the more remote islands lacked the essential services of a modern industrial economy.[21]
Some of the islands continue to contribute to modern culture. The "Mingulay Boat Song", although evocative of island life, was written after the abandonment of the island in 1938[22] andTaransay hosted theBBC television series ‘’Castaway 2000’’. Others have played a part in Scottish history. On 4 May 1746,Bonnie Prince Charlie hid onEilean Liubhaird with some of his men for four days whilstRoyal Navy vessels patrolled the Minch. They camped under a sail stretched over a "low pitiful hut" while it rained torrentially.[23]
The difficulties of definition are considerable in some cases. For example, Haswell-Smith (2004) treatsEileanan Iasgaich[Note 11] as a single island of 50 ha, although during high tides it becomes several tidal islets—none of which is ever connected to the "mainland" of South Uist. Despite its nameEilean an Taighe (English: "house island") in the Shiant Islands does not qualify for inclusion as it is connected to Garbh Eilean by a natural isthmus.

TheEileanan Chearabhaigh are a complex group of islets off the east coast of Benbecula, the area of which changes as the tides rise and fall. The total area is circa 49 hectares[19] and largest part that might be considered to be a genuine island is circa 32 hectares.[31]

Smaller islands, tidal islets only separated at higher stages of the tide, and skerries that are only exposed at lower stages of the tide pepper theNorth Atlantic surrounding the main islands. This is a continuing list of these smaller Outer Hebridean islands.[13]
Many of them are obscure and few have ever been inhabited. Nonetheless, some have a significant degree of notability. The islet on whichKisimul Castle stands is the ancient seat ofClan MacNeil andShillay in the Monach Isles had a staffed lighthouse until 1942.[32] The tiny Beasts of Holm of the east coast of Lewis were the site of the sinking of theIolaire during the first few hours of 1919,[33] one of the worst maritime disasters in United Kingdom waters during the 20th century.Calvay in the Sound of Barra provided the inspiration forCompton MacKenzie's 1947 novelWhiskey Galore after theSS Politician ran aground there with a cargo ofwhisky. Unusually for an island without permanent inhabitation, Eilean na Cille (NF847459) is connected toGrimsay (south) by acauseway.
Various Gaelic names are used repeatedly. The suffixay oraigh oraidh is generally from the Norseøy meaning "island".Eilean (plural:eileanan) also means "island".Beag andmòr (alsobheag andmhòr) mean "little" and "big" and are often found together.Sgeir is "skerry" and often refers to a rock or rocks that lie submerged at high tide.Dubh is "black",dearg is "red" andglas means "grey" or "green".Orasaigh is from the NorseÖrfirirsey meaning "tidal" or "ebb island".[34]
