Leninsky (Russian: Ле́нинский; Yakut: Ленинскай) is an urban locality (an urban-type settlement) in Aldansky District of the Sakha Republic, Russia, located 6km (04miles) from Aldan, the administrative center of the district.[2] As of the 2010 Census, its population was 1,866.
It was founded in 1926 as a gold-mining base and was known as Nizhne-Stalinsk (Russian: Ни́жне-Ста́линск) until 1962. The name referred to Joseph Stalin, with the "Nizhne-" part meaning lower, to differentiate it from the now disappeared settlements of Sredne-Stalinsk and Verkhne-Stalinsk further upstream. Urban-type settlement status was granted to it in 1932.
Within the framework of administrative divisions, the urban-type settlement of Leninsky[3] is, together with one rural locality (the selo of Yakokut), incorporated within Aldansky District as the Settlement of Leninsky. As a municipal division, the territories of the Settlement of Leninsky and the Settlement of Lebediny are incorporated within Aldansky Municipal District as Leninsky Urban Settlement.[4]
Gold mining in Leninsky stopped in 1998.
