Icelandic cattle are a breed of cattle native to Iceland. Cattle were first brought to the island during the Settlement of Iceland a thousand years ago. Icelandic cows are an especially colorful breed with a wide variety of colours and markings. Icelandic cattle have been genetically isolated for centuries, but are most closely related to a breed in Norway called Blacksided Troender- and Nordland Cattle. No cattle are permitted to be imported into Iceland, so they have been protected by strict disease-prevention measures.

The Icelandic goat, also known as the 'settlement goat'(Capra hircus), is an ancient breed of domestic goat believed to be of Norwegian origin and dating back to the settlement of Iceland over 1100 years ago. This breed of goat was on the verge of extinction during the late 19th century, but recovered prior to World War II, only to precipitously decline again. The population has dropped below 100 animals several times, leading to genetic bottleneck. As of 2003, there were 348 goats in 48 flocks distributed throughout most parts of Iceland. At the end of 2012, the herd had increased to 849. Since this breed has been isolated for centuries, the Icelandic populations are highly inbred. The Icelandic goat is very rare outside its native land. Under its coarse, long guard hair, the Icelandic goat has a coat of high quality cashmere fiber. Icelandic goats are kept mainly as pets and their economic potential for meat, milk, cashmere and skin production remains to be explored. The Icelandic goat is currently of little economic value.
