Tommot (Russian: Томмо́т; Yakut: Томмот) is a town in Aldansky District of the Sakha Republic, Russia, located on the Aldan River (a right-hand tributary of the Lena) 390 kilometers (240 mi) southwest of Yakutsk, the capital of the republic, and 70 kilometers (43 mi) southwest of Aldan, the administrative center of the district. As of the 2010 Census, its population was 8,057.
The name of the town is derived from a Yakut word meaning non-freezing.
The town was the terminus of the passenger trains of the Amur–Yakutsk Mainline. In November 2011, the railway was extended to Nizhny Bestyakh; it will eventually reach Yakutsk. Both the railway and the Lena Highway cross the Aldan at this point.
It was founded in 1923 with the construction of a river port on the Aldan for supplies to the Nezametny gold mine in the present-day town of Aldan. It was formerly the head of navigation of the Aldan River. Tommot was granted town status in 1925.
