Municipal okrug of Primorsky District of the federal city of St. Petersburg, Russia, comprising that city's historical areas of Lakhta and Olgino. It is located just north of the Gulf of Finland. Population: 3,903 (2010 Census).

The municipality of Lakhta was historically populated with Finns, though it never was part of Finland, as Finland only gained its independence in 1917. By the 1880s approximately 80% of the peasants were Finnish and spoke poor Russian. Lakhta is located on the Karelian isthmus, in Northern Ingria near historic Finnish Karelia.
