Shetland, also called the Shetland Islands, is an archipelago in Scotland lying between Orkney, the Faroe Islands, and Norway. It is 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. Their total area is 566 sq mi (1,466 km²), and the population totalled 22,920 in 2019. The islands comprise the Shetland constituency of the Scottish Parliament. The local authority, the Shetland Islands Council, is one of the 32 council areas of Scotland. 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.

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.
