Chukchi, also spelled Chukchee, also called Luorawetlan, people inhabiting the northeasternmost part of Siberia, the Chukotskiy (Chukotka) autonomous okrug (district) in Russia. They numbered 14,000 in the late 20th century and are divided into two chief subgroups, reindeer Chukchi and maritime Chukchi. The reindeer Chukchi inhabit the interior of the easternmost portion of the okrug, the Chukotskiy (Chukchi) Peninsula, and its Siberian hinterland; the maritime Chukchi inhabit the Arctic and Bering coasts. Both speak a Luorawetlan language of the Paleosiberian language group and are linguistically and culturally related to the Koryak and Itelmen (Kamchadal).
The reindeer Chukchi formerly lived mainly off of domesticated herds of reindeer. These herds supplied them with means of transport, milk and meat for food, and pelts for clothing and shelter. The maritime Chukchi lived by hunting Arctic sea mammals, chiefly walrus, seals, and whales, and by fishing.
Their traditional dwellings varied according to their subsistence pattern. Maritime Chukchi lived in fixed villages; their houses were semisubterranean. Reindeer Chukchi were nomadic and lived in tents, changing residence according to seasonal change in pasture. Transportation depended on sledges pulled by reindeer or dogs harnessed in pairs. The maritime Chukchi traveled in boats with wooden frames and skin covers. The basic socioeconomic unit of the maritime Chukchi was the boat team of several related families; it sometimes included neighbours. The village was a territorial association of related and unrelated families. Among the reindeer Chukchi, the encampment of families who herded together was the basic economic unit.
According to Chukchi religion, invisible spirits populate the universe. Sacrifices were an important aspect of the major festivals. Shamanist ceremonies were conducted for divination and healing.
After the Russian Revolution the Chukchi were settled on collective farms. Technical improvements and new economic activities have been introduced among them.
