Koltur is an island in the Faroe Islands, located to the west of Streymoy and to the north of Hestur. The island has just one settlement: Koltur. It was abandoned in the 1980s by the sheep-farmers whose flocks grazed on the southern part of the island. Since then only two people have returned (in 1994), and they are working on restoring the village. Koltur has one mountain: Kolturshamar (478 m).
