Languages

The official languages are both Russian and Sakha, also known as Yakut, which is spoken by roughly half of the republic's population. In the 2021 census, 95% of Yakuts, 72% of Evenks and 60% of Evens declared Sakha as their native language. The Sakha language is a member of the Turkic language family, belonging to the Siberian branch. It is closely related to the Dolgan language of the former Taymyr Dolgano-Nenets Autonomous Okrug.

The Sakha Republic is also home to many of the world's speakers of Tungusic languages, primarily of Evenki and Even. Additionally, Chukchi and the lects of the Yukaghir language family are spoken in the northeast.
