The Demyanka River (Russian: Демьянка) is a river in Russia. It is the right tributary of the Irtysh River. The river's source lies in the Vasyugan Swamp.
The river bed is unbranched, strongly meandering. The bottom of the river bed is either ooze or sandy. During the spring rise of the water level, the river partially becomes navigable. The riverbed in shallow water is cluttered with fallen trees and bushes. The sloping longitudinal slope is insignificant - 0.034 ‰. Ice drifting takes place on the rise of high water.
The Demyanka basin is significantly swampy and is characterized by a huge number of small lakes: marshiness 50%, forest cover 45%. The lake is not so large and does not exceed 2.0%, which is caused by the extremely small size of the inter-hollow lakes.
On the river there is a settlement of Demianka, but on the whole the Demianka basin is weakly populated. There are no large settlements.
