Leninsky (Russian: Ле́нинский; Yakut: Ленинскай) is an urban locality (an urban-type settlement) in Aldansky District of the Sakha Republic, Russia, located 6 kilometers (3.7 mi) from Aldan, the administrative center of the district.

[citation needed] 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.

[2] Within the framework of administrative divisions, the urban-type settlement of Leninsky[1] is, together with one rural locality (the selo of Yakokut), incorporated within Aldansky District as the Settlement of Leninsky.

[citation needed] The Amur–Yakutsk Mainline railway passes nearby, as does the A360 Lena Highway to Yakutsk.
