The Besermyan, Biserman, Besermans, or Besermens, are a numerically small Permian people in Russia.
The Besermyan live in the districts of Yukamenskoye, Glazov, Balezino, and Yar in the northwest of Udmurtia. There are ten villages of pure Besermyan ethnicity in Russia, and 41 villages with a partial Besermyan population.

History
The Besermyan are of mixed origin, and are probably the result of a group of Tatars who were assimilated by the Udmurts. In the 13th century, during his travel to Mongolia, papal envoy Plano Carpini claimed that the Besermyan were subjects of the Mongols. Russian chronicles sometimes made mention of the Besermyan but it's unclear whether the term was meant to denote the modern group as it was a common derivation of the term "musulman" (Muslim). Although they speak a dialect of Udmurt, the Besermyan consider themselves a distinct people.
The Besermyan used to historically practice their own indigenous religion. According to scholar Shirin Akiner, most current Besermyan practice Sunni Islam. Some Besermyan also practice Christianity.]]
In a mtDNA research which was done on Besermyans there were 41 tested persons from the village of Yozhovo in Yukamenskovo raion of Udmurtia. The proportion of Eastern Eurasian haplogroups, primarily of haplogroup C, turned out to be significantly higher than that of the Udmurts. According to this indicator, the Besermyans genetically stand out against the background of the Volga-Ural region and are closer to the Turkic-speaking peoples of Southern Siberia.
A study was conducted of the Y-chromosome haplogroups of 53 Besermyans from the villages of Yukamenskoye and Yozhevo, as well as the village of Shamardan, Yukamensky district of Udmurtia. It turned out that more than half of the samples belong to haplogroup N, which may indicate the predominance of the Finno-Ugric component in the formation of the Besermyans along their male line.
The data from lexicostatistics also did not reveal a noticeable Bulgar (Old Chuvash) substrate in the Besermyan dialect. Only Tatar adstrate, associated with the Chepetsk Tatars, can be traced.
According to a 2019 study, the Besermyan's autosomal genetic admixture can be modeled as two-thirds Srubnaya-like and about one-third Nganasan-like.
