Priozersk (Russian: Приозе́рск; Finnish: Käkisalmi; Swedish: Kexholm) is a town and the administrative center of Priozersky District in Leningrad Oblast, Russia, located at the northwestern shore of Lake Ladoga, at the estuary of the northern armlet of the Vuoksi River on the Karelian Isthmus.

Russia definitively secured the area during the Great Northern War; the town's Swedish name was retained, however, as Keksgolm (Кексгольм).

Eventually, after hard fighting, Finland was forced to cede Käkisalmi and the eastern portion of Finnish Karelia to the Soviet Union by the terms of the 1940 Moscow Peace Treaty.

[9] On November 24, 1944, Keksgolmsky District was transferred from the Karelo-Finnish Soviet Socialist Republic to Leningrad Oblast.

Priozersk was settled with mainly Russians, Belarusian, and Ukrainian migrants, who have since comprised the majority of the local population.

[1] As an administrative division, it is, together with three rural localities, incorporated within Priozersky District as Priozerskoye Settlement Municipal Formation.

The ramparts and towers of the fortress are located on the bank of the Vuoksi, still visible when traveling to the town from St. Petersburg.
