Omsk (/ˈɒmsk/; Russian: Омск, IPA: [omsk]) is the administrative center and largest city of Omsk Oblast, Russia. It is situated in southwestern Siberia and has a population of over one million. Omsk is the third largest city in Siberia after Novosibirsk and Krasnoyarsk, and the twelfth-largest city in Russia. It is an important transport node, serving as a train station for the Trans-Siberian Railway and as a staging post for the Irtysh River.
During the Imperial era, Omsk was the seat of the Governor General of Western Siberia and, later, of the Governor General of the Steppes. For a brief period during the Russian Civil War in 1918–1920, it served as the capital of the anti-Bolshevik Russian State and held the imperial gold reserves.

Siberian Tatar (Татарца, Tatartsa) is a Turkic language spoken by about 140,000 people in Western Siberia, Russia, primarily in the oblasts of Tyumen, Novosibirsk, Omsk, Tomsk and Kemerovo Oblasts, but also in Sverdlovsk Oblast. According to Marcel Erdal, due to its particular characteristics, Siberian Tatar can be considered as a bridge between Kipchak and Siberian Turkic languages.
