Kuznechnoye (Russian: Кузне́чное; Finnish: Kaarlahti) is an urban locality (an urban-type settlement) in the northern part of Priozersky District of Leningrad Oblast, located on the Karelian Isthmus.

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

[9] In the end of 1944 a large granite quarry and processing plant (now belonging to JSC Granit-Kuznechnoye) was developed, and Kaarlahti started to grow steadily.

The granite excavated from Kuznechnoye, during the Soviet era, has been used to build the St. Petersburg Metro Station and to pave many central streets of the city.

[10] Kuznechnoye is also an important station of the Saint Petersburg-Khiytola railroad, being the final destination of many passenger trains coming from Finlyandsky Rail Terminal of St. Petersburg (about 3 h 25 min as of 2007) and from Sortavala (about 2 h 45 min as of 2007) and a stop of the St. Petersburg–Kostomuksha trains.
