The Kyuyonelekeen (Russian: Кюёнэлэкээн; Yakut: Күөнэлэкээн, Küönelekeen), also spelled as Kyuyonelekyan[1] and Kyuenelekyan,[2] is a river in Yakutia (Sakha Republic) and Krasnoyarsk Krai, Russia.

The nearest settlement is Olenyok village, Olenyoksky District, located to the east of its mouth.

The river flows roughly southwards across mountainous taiga, to the west of the Kengeede.

Finally it joins the left bank of the Arga-Sala river 118 km (73 mi) from its mouth in the Olenyok.

[4][2] The river is frozen between the first half of October and late May or early June.
