Lake Kubenskoye (Russian: Кубенское озеро) is a large and shallow lake in Vologda Oblast of Russia, situated at the height of 110.1 metres above mean sea level, stretching for 54 km from north-west to south-east.

The lake is known for its frequents storms and seasonal fluctuations of water level.

It is the source of the river Sukhona, which flows out in the southeastern corner of the lake.

The eastern terminus of the Northern Dvina Canal is at the northwestern end of the lake.

In 1917, a dam was built at the outflow of the Sukhona, thus converting the lake into a reservoir.
