The Icelandic is the Icelandic breed of domestic sheep. It belongs to the Northern European Short-tailed group of sheep, and is larger than most breeds in that group. It is thought to have been introduced to Iceland by Vikings in the late ninth or early tenth century.

It is generally short-legged and stocky, slender and light-boned, and usually horned, although polled and polycerate animals can occur; there is a polled strain, the Kleifa. The fleece is double-coated and may be white or a variety of other colors; the face and legs are without wool. The sheep are highly resistant to cold, and are generally left unshorn for the winter. Icelandic ewes are highly prolific, with a lambing percentage of 175–220%. The Þoka (Thoka) gene is carried by some ewes, which may give birth to large litters of lambs. A unique strain within the population is the Leadersheep, which carries a hereditary ability or predisposition to lead other sheep safely over dangerous ground.

History

It is thought that the sheep were introduced to Iceland by Vikings in the late ninth or early tenth century.

Breed numbers reached a peak in 1978, when there were approximately , or about four sheep for every inhabitant of Iceland. By 2007 the total number had fallen to about . In 2018, a population of just over was reported to DAD-IS. As of 2025, the sheep population is 365,290.

Characteristics

The colors of Icelandic sheep are inherited in a similar way to those of other sheep, but they display more variety in color and pattern than most other breeds, and some variations are seen which are not seen in other sheep. Each sheep carries three genes that affect the color of the sheep, and each gene has dominant and recessive alleles.

Use

Until the 1940s it was the predominant milk-producing animal in Iceland. In the twenty-first century it is reared principally for meat, which accounts for more than 80% of the total income derived from sheep farming.

The fleece is double-coated, with a long outer coat (tog) which gives protection from snow and rain, and a fine inner coat (þel) which insulates the animal against the cold. The wool of the outer coat has a diameter of about or sometimes more, and a staple length of some ; the inner coat has a diameter of or sometimes less, with a staple length in the range . The two types may be used separately, or spun into a single yarn, lopi, a soft wool which provides good insulation.
