Khanty-Mansiysk (Russian: Ха́нты-Манси́йск, romanized: Khánty-Mansíysk, lit. Khanty-Mansi Town; Khanty: Ёмвоҷ, Jomvoćś; Mansi: Абга, Abga) is a city in west-central Russia. Technically, it is situated on the eastern bank of the Irtysh River, 15 kilometers (9.3 mi) from its confluence with the Ob, in the oil-rich region of Western Siberia. Though it is an independent city, Khanty-Mansiysk also functions as the administrative centre of Khanty-Mansiysky District, and the administrative center of Khanty-Mansi Autonomous Okrug–Yugra.
With 101,466 estimated inhabitants, Khanty-Mansiysk is among Russia's few regional capitals that are not the largest cities in their surrounding area, as it is surpassed in population by Surgut, Nizhnevartovsk and Nefteyugansk.
