The Lakharchana (Russian: Лахарчана; Yakut: Лахарчаана, romanized: Laxarçâna), is a river in Yakutia (Sakha Republic), Russia.

[4] About midway through its course it bends and flows roughly southeastwards meandering in a floodplain among smooth hills.

Finally, it meets the left bank of the Vilyuy 1,831 km (1,138 mi) from its mouth in the Lena.

[5][6] The main tributary of the river, longer than the Lakharchana itself, is the 204 kilometres (127 mi) long Khakhsyk joining it from the right.

The Lakharchana freezes in mid October and stays under ice until late May.
