Siberian Tatar — known to its speakers as сыбыр тел (sıbır tel) — is a Kipchak Turkic language spoken by approximately 100,000 people across the western Siberian oblasts of Tyumen, Omsk, Novosibirsk, Tomsk, and Kemerovo in Russia. Distinct from standard Volga Tatar, the language comprises three main dialect groups — Tobol-Irtysh, Baraba, and Tom — and is considered endangered, with self-identification among census respondents numbering fewer than 10,000. The Siberian Tatars traditionally call themselves Yerle Qalıq ("older inhabitants") to distinguish themselves from later Volga Tatar settlers in the region. The Institute for Bible Translation (IBT), whose operational center transferred from Stockholm to Moscow in 2003, has led the translation of Scripture into Siberian Tatar, publishing the Book of Jonah in 2019, the Books of Ruth and Esther in 2022, and the Gospel of Mark — the first full New Testament book — in 2025. The audio recordings are hosted's Bible.is platform, accompanying video resources that make these inaugural portions of Scripture accessible to Siberian Tatar-speaking communities.
