The Kyuyutingde (Russian: Кюютингдэ)[1] is a river in Yakutia (Sakha Republic), Russia.

[2] It flows north of the Arctic Circle across a desolate area of Bulunsky District devoid of settlements and joins the Olenyok in its final major bend, where it begins to head northwards until the Laptev Sea.

Its sources are at the southern end of the Kystyk Plateau at the confluence of the 58 kilometres (36 mi) long Debengde and the 40 kilometres (25 mi) long Sygynakhtaakh.

It flows first in a roughly southeastern direction, then it bends southwestwards for a short stretch and bends finally westwards, heading in that direction until the Olenyok floodplain, where it enters a low, marshy area with many small lakes to the north.

It meanders strongly until it joins the great river 392 km (244 mi) upstream of its mouth.
