The Kuoyka or Kuoika (Russian: Куойка; Yakut: Куойка) is a river in Yakutia (Sakha Republic), Russian Federation. It is a tributary of the Olenyok with a length of 294 kilometres (183 mi) and a drainage basin area of 4,750 square kilometres (1,830 sq mi). The Kuoyka flows north of the Arctic Circle across a lonely, desolate area of the Olenyoksky District devoid of settlements.
The name of the river comes from the Nganasan word "kuoika", (куойка), meaning a household deity.
