The 558 km long Sukhona (Russian Сухона ) is a river in the Vologda Oblast in northwestern Russia.

The fully navigable river entfließt the Kubenasee ( Кубенское озеро ), which is fed by the Kubena. From there, it flows through a swampy lowland mostly in an easterly direction until after Veliky Ustjug to unite there with the coming of the south Jug for Northern Dvina. The mean river discharge in the vicinity of the mouth is 456 m³ / s, but can rise in spring to 6520 m³ / s. It may be caused by strong inflow from the Vologda and Lescha and due to the small gap at the upper course of the river for temporary reversal of the flow direction in the direction Kubenasee. In summer, however, the discharge rate decreases up to 17.6 m³ / s, which leads to disruption of shipping traffic. The end of October or in November the Sukhona starts to freeze in December and the middle of the river. The ice cover opens only in the latter part of April or the first half of May.

Through a channel that connects the Kubenasee with the Volga - Baltic Canal, the Sukhona and the Northern Dvina are connected to the Russian domestic air duct system.

The Sukhona that is longer than the jug, and the several hundred kilometers long Kubena can as the actual - are considered source rivers of the Northern Dvina, because they are longer than any other tributary - merging.
