石泉通古斯河（Подкаменная Тунгуска），又称中通古斯河，是叶尼塞河右岸主要支流之一，发源于中西伯利亚高原，在克拉斯诺亚尔斯克边疆区境内汇入叶尼塞河。该河全长1865公里，流域面积约24万平方公里。1908年通古斯大爆炸即发生在该河流域。

The Podkamennaya Tunguska (Russian:Подкаменная Тунгуска, literally Tunguska under the stones, also Middle Tunguska or Stony Tunguska) is a river in Krasnoyarsk Krai, Russia. It is an eastern tributary of the Yenisei and has a length of 1,160 miles (1,870 km). The name of the river comes from the fact that it flows under pebble fields without open water. As early as 1610 Russians from Mangazeya had passed the Stony Tunguska's confluence with the Yenisei; by the 1620s Mangazeya Cossacks and trappers had ascended it seeking fur-tribute from the local Tungus clans. The Tunguska event in June 1908 occurred near this river, some 8 km (5.0 mi) SSE of Lake Cheko.
