The Anabar River (Russian: Анабар) is a river in Sakha, Russia, located just west of the Lena River. Its catchment extends into the Putoran Mountains that form the highest part of the Central Siberian Plateau.Its mean annual discharge is approximately 500 cubic metres per second (18,000 cu ft/s), concentrated heavily in early summer when the ice that covers the river for most of the year thaws.
