The Pokshenga (Russian: Покшенга, Покшеньга) is a river in Vinogradovsky and Pinezhsky Districts of Arkhangelsk Oblast in Russia.

The principal tributaries of the Pokshenga are Shatogorka (right), Okhtoma (left), Pilmenga (right), and Shilmusha (right).

After accepting the left tributary, the Kosvey, the Pokshenga departs from the border and turns north-east.

The mouth of the Pokshenga is located close to the village of Kobelevo, downstream from the district center of Karpogory.

The merchants were going from the Northern Dvina upstream the Pukshenga, then moved to the Pokshenga and went downstream to the Pinega.
