Yarensk (Russian: Я́ренск) is a rural locality (a selo) and the administrative center of Lensky District of Arkhangelsk Oblast, Russia, located on the bank of the Vychegda River near its confluence with the Yarenga.

[6] The town of Yarensk was documented as early as 1384 as a station on the road leading from Novgorod to the Ural Mountains.

In the Russian Empire, it was the seat of a huge uyezd within Vologda Governorate.

The Tsar used the town as a place of exile, most notably for Prince Vasily Galitzine.

The modern village has a mid-18th century Orthodox cathedral adapted for use as a local history museum.
