Fetlar shown within Shetland Islands

Fetlar is one of the North Isles of Shetland, Scotland, with a population of about 100 people. Its main settlement is Haibie on the south coast, home to the Fetlar Interpretative Centre .

The northern part of Fetlar is a RSPB reserve, home to several important breeding species including Arctic Skuas, Whimbrels. Of greatest importance though are Red-necked Phalaropes, for which Loch of Funzie is the most important breeding site in the United Kingdom, and for a while during the 1990s was the only breeding site in the country. Snowy Owls, which were discovered breeding here in the 1960s, lasted until the 1980s but are no longer present, except as a rare visitor.

Another attraction on the island is Brough Lodge , built by Arthur Nicolson in the 1820s.

Ferries sail from Oddsta on Fetlar to Gutcher on Yell and Belmont on Unst.
