The Ygyatta (Russian: Ыгыатта, [ɨɡɨɐˈta]; Yakut: Ыгыатта, Igıatta)[1] is a river in Sakha, Russia. It is a left tributary of the Vilyuy. The Ygyatta is 601 kilometres (373 mi) long, and its basin covers about 11,200 square kilometres (4,300 sq mi).[2] The depth of the river at its mouth is near 10 metres (33 ft). It rises on the Vilyuy Plateau in the west of Sakha and is fed by rain and snowmelt.[3]

The river and its banks are rich with gems: emeralds, rubies, sards, aquamarines, and others.

There are goldfields along the river.

The basin of the Ygyatta is among the least populated places within Russia.
