The Mainland is the main island of Shetland, Scotland. The island contains Shetland's only burgh, Lerwick, and is the centre of Shetland's ferry and air connections.
The North Mainland – in particular the large Northmavine peninsula, connected to Mainland by a narrow isthmus at Mavis Grind – is wild, with much moorland and coastal cliffs. The North Mainland contains Sullom Voe, the location of an oil terminal providing an important source of employment for islanders.
