The Stony Tunguska (Russian: Подкаменная Тунгуска, Podkamennaya Tunguska, literally Understone Tunguska) is a river in Siberia; it is a right tributary of the Yenisei and has a length of 1865 km. The name of the river comes from the fact that its significant stretches flow under pebble fields without open water. It is known for the Tunguska event.
