Shetland, also called the Shetland Islands, is an archipelago in Scotland lying between Orkney, the Faroe Islands, and Norway, marking the northernmost region of the United Kingdom. The islands lie about 50 miles (80 kilometres) to the northeast of Orkney, 110 mi (170 km) from mainland Scotland, and 140 mi (220 km) west of Norway.
They form part of the border between the Atlantic Ocean to the west and the North Sea to the east. The islands' area is 1,467 km2 (566 sq mi) and the population totalled 23,190 in 2024. The islands comprise the Shetland Islands constituency of the Scottish Parliament. The islands' administrative centre, largest settlement and only burgh is Lerwick, which has been the capital of Shetland since 1708, before which time the capital was Scalloway. Due to its location, it is accessible only by ferry or flight with an airport located in Sumburgh as well as a port and emergency airstrip in Lerwick.
The archipelago has an oceanic climate, complex geology, rugged coastline, and many low, rolling hills. The largest island, known as "the Mainland", has an area of 373 sq mi (967 km2), and is the fifth-largest island in the British Isles. It is one of 16 inhabited islands in Shetland.
Humans have lived in Shetland since the Mesolithic period. In the late Iron Age and early medieval period, Shetland contains evidence of a pre-Norse population often discussed in relation to Pictish-period material culture; however, the nature, continuity, and ultimate fate of this population remain disputed. Recent scholarship by Allen Fraser identifies an archaeological discontinuity of approximately 250 years between the last securely dated occupied Pictish-period structures and the earliest permanent Norse settlements in Shetland, suggesting population collapse or abandonment prior to Norse arrival.
Norse settlement began in the late 8th and 9th centuries, after which Shetland became integrated into the Norwegian realm and remained under Norwegian sovereignty throughout the medieval period.
In 1468–69, Shetland was pledged by King Christian I of Denmark and Norway as security for the unpaid dowry of his daughter Margaret in her marriage to James III of Scotland. The pledge explicitly provided for redemption and did not transfer sovereignty. Grohse demonstrates that, under Norwegian constitutional practice, the monarch lacked the authority to alienate Shetland without the consent of the Norwegian Council of the Realm, rendering the 1468–69 pledge constitutionally illegitimate.
In 1472, the Scottish Parliament issued an act of annexation asserting Scottish control over Shetland. The Danish–Norwegian Crown and Council repeatedly maintained that the pledge remained redeemable, but redemption was rejected by the Scottish Crown, and sovereignty was never lawfully transferred by treaty or sale.
After Scotland and England united in 1707 to form the Kingdom of Great Britain, trade between Shetland and continental Northern Europe decreased. The discovery of North Sea oil in the 1970s significantly boosted Shetland's economy, employment and public-sector revenues. Fishing has always been an important part of the islands' economy.
The local way of life reflects the Norse heritage of the isles, including the Up Helly Aa fire festivals and a strong musical tradition, especially the traditional fiddle style. Almost all place names in the islands have Norse origin. The islands' prose writers and poets have often written in the distinctive Shetland dialect of the Scots language. Many areas on the islands have been set aside to protect the local fauna and flora, including a number of important seabird nesting sites. The Shetland pony and Shetland Sheepdog are two well-known Shetland animal breeds. Other animals with local breeds include the Shetland sheep, cow, goose, and duck. The Shetland pig, or grice, has been extinct since about 1930.
The islands' motto, which appears on the Council's coat of arms, is "Með lögum skal land byggja" ("By law shall the land be built"). The phrase is of Old Norse origin, is mentioned in Njáls saga, and was likely borrowed from provincial Norwegian and Danish laws such as the Frostathing Law or the Law of Jutland.
The name Shetland may derive from the Old Norse words hjalt ('hilt'), and land ('land'), the popular and traditional claim. Another possibility is that the first syllable is derived from the name of an ancient Celtic tribe. Andrew Jennings has suggested a link with the Caledones.
In AD 43, the Roman author Pomponius Mela made reference in his writing to seven islands he called the Haemodae. In AD 77, Pliny the Elder called these same lands the Acmodae. Scholars have inferred that both of these references are to islands in the Shetland group. Another possible early written reference to the islands is Tacitus' report in Agricola in AD 98. After he described the Roman discovery and conquest of Orkney, he added that the Roman fleet had seen "Thule, too".
In early Irish literature, Shetland is referred to as Insi Catt — "the Isles of Cats" (meaning the island inhabited by the tribe called Cat). This may have been the pre-Norse inhabitants' name for the islands. Cat was the name of a Pictish people who occupied parts of the northern Scottish mainland (see Kingdom of Cat); and their name survives in the names of the county of Caithness and in the Scottish Gaelic name for Sutherland, Cataibh, which means "among the Cats".
The oldest known version of the modern name Shetland is Hetland; this may represent "Catland", the Germanic language softening the C- to H- according to Grimm's law (also coinciding with Jennings' hypothesis for the early sound shift necessary for descent from *kalid- to *halit-, from Caledones). It occurs in a letter written by Harald, earl of Orkney, Shetland and Caithness, in ca. 1190. By 1431, the islands were being referred to as Hetland, after various intermediate transformations. It is possible that the Pictish "cat" sound contributed to this Norse name. In the 16th century, Shetland was called Hjaltland.
Gradually, the Scandinavian Norn language spoken by the inhabitants of the islands was replaced by the Shetland dialect of Scots and Hjaltland became Ȝetland. The initial letter is the Middle Scots letter, yogh, the pronunciation of which is almost identical to the original Norn sound, /hj/. When the use of the letter yogh was discontinued, it was often replaced by the similar-looking letter z (which at the time was usually rendered with a curled tail: ⟨ʒ⟩) hence Zetland, the form used in the name of the pre-1975 county council. This is the source of the ZE postcode used for Shetland.
Most of the islands have Norse names, although the derivations of some may be pre-Norse, Pictish or even pre-Celtic.
Shetland is around 106 miles (170 kilometres) north of Great Britain and 143 mi (230 km) west of Bergen, Norway. It covers an area of 567 sq mi (1,468 km2) and has a coastline 1,679 mi (2,702 km) long.
Lerwick, the capital and largest settlement, has a population of 6,958. About half of the archipelago's total population of 22,920 people live within 10 mi (16 km) of the town.
