The Tyung (; Yakut: Түҥ, Tüŋ) is a river in Yakutia, Russia. It is a left tributary of the Vilyuy (Lena's basin). The length of the river is 1092km (679miles). The area of its basin is 49800km2.
The Tyung begins in the Central Siberian Plateau. When it descends into the Central Yakutian Lowland it begins to meander strongly and flows roughly southwards until it meets the Vilyuy. The Tyukyan, also a Vilyuy tributary, has its source in a swampy area near the Tyung basin.[1]
The Tyung freezes up in October and stays icebound until the second half of May to early June.
Its main tributaries are the 299km (186miles) long Chimidikyan (Чимидикээн), the 243km (151miles) long Dzhippa (Дьыыппа), the 193km (120miles) long Arga-Tyung (Арҕаа Түҥ) and the 174km (108miles) long Tyungkeen (Түҥкэн).
