The Yukaghirs, or Yukagirs (одул, деткиль (), юкаги́ры), are a Siberian ethnic group in the Russian Far East, living in the basin of the Kolyma River.
The Tundra Yukaghirs live in the Lower Kolyma region in the Sakha Republic; the Taiga Yukaghirs in the Upper Kolyma region in the Sakha Republic and in Srednekansky District of Magadan Oblast. By the time of Russian colonization in the 17th century, the Yukaghir tribal groups occupied territories from the Lena River to the mouth of the Anadyr River. The number of the Yukaghirs decreased between the 17th and 19th centuries due to epidemics, internecine wars and Tsarist colonial policy which may have included genocide against the sedentary hunter-fisher Anaouls. Some of the Yukaghirs have assimilated with the Yakuts, Evens, and Russians.
Currently, Yukaghirs live in the Sakha Republic and the Chukotka Autonomous Okrug of the Russian Federation. According to the 2002 Census, their total number was 1,509 people, up from 1,112 recorded in the 1989 Census.
According to the latest 2001 all Ukrainian census, 12 Yukaghirs are living in Ukraine. Only 2 of them indicated Yukaghir as their native language. For the remaining others (6) it is Russian and for 1 it is some other tongue.
Genetically, Yukaghirs exhibit roughly equal frequencies of the Y-DNA haplogroups N1c, Q1, and C2 (formerly C3).
According to another study, out of 11 Yukaghir males 3 turned out to belong to the Y-haplogroup N1c (different subclade from the one found in Yakuts), another 4 - to the Y-haplogroup C2 (former C3; for the most part, the same subclade that's also found in Koryaks), one more - to the Y-haplogroup O, and the rest 3 exhibit apparent Russian genetic influence (two individuals belonging to the Y-haplogroup R1a, and one more - to the Y-haplogroup I2a). The study also found no similarities between Yukaghirs and Chukchis in regards to mitochondrial DNA.
The 13 tribes that once constituted the Yukaghir group are: Vadul-Alais, Odul, Chuvan, Anaoul, Lavren, Olyuben, Omok, Penjin, Khodynts, Khoromoy, Shoromboy, Yandin, and Yandyr.
