The Kamasins (Russian: камасинцы, romanized: kamasintsy; Kamassian: Kaŋmažə)[1] are a collection of tribes of Samoyedic peoples in the Sayan Mountains who lived along the Kan River and Mana River in the 17th century in the southern part of today's Krasnoyarsk Krai.

In the Russian 2010 and 2021 censuses, two people identified as Kamassian and listed under the subgroup "other nationalities".

[4] The origins of the Kamasins remain obscure but it is believed that they are descended from Proto-Samoyed tribes.

Around the 17th century, the Kamasins moved and settled along the Kan and Mana rivers.

The Taiga Kamasins spoke the Kamass dialect of Kamassian until the early 20th century.
