The Mezen (Russian: Мезень; Komi: Мозын, Mozyn) is a river in Udorsky District of the Komi Republic and in Leshukonsky and Mezensky Districts of Arkhangelsk Oblast in Russia. Its mouth is located in the Mezen Bay of the White Sea. Mezen is one of the biggest rivers of European Russia. It is 966 kilometres (600 mi) long, and the area of its basin 78,000 square kilometres (30,000 sq mi). The principal tributaries of the Mezen are the Bolshaya Loptyuga (left), the Pyssa (left), the Mezenskaya Pizhma (right), the Sula (right), the Kyma (right), the Vashka (left), the Pyoza (right), and the Kimzha (left).

The river basin of the Mezen comprises vast areas in the east and north-east of Arkhangelsk Oblast and in the west of the Komi Republic. The town of Mezen, the urban type settlements of Usogorsk and Kamenka, as well as the administrative center of Udorsky District, the selo of Koslan all are located on the banks of the Mezen. The administrative center of Leshukonsky District, the selo of Leshukonskoye, is located on the Vashka River several kilometers upstream from the confluence of the Vashka and the Mezen and is connected with the right bank of the Mezen by a ferry crossing.

The source of the Mezen is in the Timan Ridge in the Komi Republic, west of the northern Ural Mountains. It flows first south-west, then sharply turns roughly in the north-western direction. The upper course of the Mezen runs through the hilly landscape. The Mezen flows into the Mezen Bay of the White Sea near the town of Mezen, right below the Arctic Circle. Near its mouth, the Pyoza River enters from the east.

The Mezen is navigable below the selo of Koslan, however, there is no regular passenger navigation except for ferry crossings.
