Kölükök () is a mountain lake in the Naryn Region of Kyrgyzstan (Central Asia).
Kölükök is located about south-southeast of the town Kochkor in the western foothills of the Terskey Ala-too. The approximately 2.5 km long lake with SSE-NNW orientation has an area of 1.22 km2 and is located at an altitude of 2970 m. The Ükök, outflow of the lake, initially flows in a north-westerly and later in a northerly direction through the mountains before reaching a plateau, flowing through the town of Kochkor and flowing into the river Chu on the right.
The catchment contains small glaciers with a total area exceeding 7 km². Inflowing water seeps through beneath the rock-debris dam before emerging downstream.
The lake was formed when a trough-shaped valley formerly occupied by a glacier was blocked by moraines and rockfall debris.
