The Chona (Russian: Чона; Yakut: Чуона, Çuona) is a river in the Sakha Republic (Yakutia) and Irkutsk Oblast, Russia. It is a right hand tributary of the Vilyuy, and is 802 kilometres (498 mi) long, with a drainage basin of 40,600 square kilometres (15,700 sq mi).

The Russian Geographical Society organized an expedition in 1853–55 to survey the orography, geology and population of the Vilyuy and Chona basins.
