Autonomous okrug is a term for an administrative country subdivision in Russia. The term was also used in the Soviet Union.

The Nenets (Nenets: ненэцяˮ, Russian: ненцы), also known as Samoyeds, are an indigenous people in northern arctic Russia. According to the latest census in 2002, there are 41,302 Nenets in the Russian Federation, most of them living in the Yamalo-Nenets Autonomous Okrug and Nenets Autonomous Okrug. They speak either the Tundra or Forest varieties of Nenets.

Due to a false etymology, the name Samoyed entered the Russian language as a corruption of the self-reference Saamod, Saamid (the Samoyedic suffix "-d" denotes plurality). It is the same as Saami (formerly Lapps or Lapons) in Finland, and Suomi, the Finnish name of Finland. In Russian ethnographic literature of the 19th century, they were also called "Самоядь", "Самодь", (samoyad', samod', samodijtsy, samodijskie narody) which was often transliterated into English as Samodi.

The literal morphs samo and yed in Russian convey the meaning "self-eater", which appears as derogatory. Therefore the name Samoyed quickly went out of usage in the 20th century, and the people bear the name of Nenets, which means "man".

The Chukchi, or Chukchee (Russian: чукчи (plural), чукча (singular)) are an indigenous people inhabiting the Chukchi Peninsula and the shores of the Chukchi Sea and the Bering Sea region of the Arctic Ocean within the Russian Federation. They speak the Chukchi language. The Chukchi originated from the people living around the Okhotsk Sea.

The majority of Chukchi reside within Chukotka Autonomous Okrug, but some also reside in the neighboring Sakha Republic to the west, Magadan Oblast to the southwest, and Koryak Autonomous Okrug to the south. Some Chukchi also reside in other parts of Russia, as well as in Europe and North America. The total number of Chukchi in the world slightly exceeds 15,000.

The Chukchi are traditionally divided into the Maritime Chukchi, who had settled homes on the coast and lived primarily from sea mammal hunting, and the Reindeer Chukchi, who nomadised in the inland tundra region with their herds of reindeer. The Russian name "Chukchi" is derived from the Chukchi word Chauchu ("rich in reindeer"), which was used by the 'Reindeer Chukchi' to distinguish themselves from the 'Maritime Chukchi,' called Anqallyt ("the sea people"). The indigenous name for a member of the Chukchi ethnic group as a whole is Luoravetlan (literally 'true person').
