Song-Köl (Kyrgyz: Соң-Көл,[2] IPA: [ˈsoŋkøl], also Соңкөл Songköl,[3] literally "following lake", Russian: Сон-Куль, romanized: Son-Kul',[4] also Сонкёль Sonkyol'[5]) is an alpine lake in northern Naryn Region, Kyrgyzstan.

The lake sits in the central part of Song-Köl Valley surrounded by Songköl Too ridge from the north, and Borbor Alabas and Moldo Too mountains from the south.

Four perennial rivers - Kumbel, Aktash, Tashdöbö, and Karakeche - disgorge themselves into the lake.

In the south-east, the structural high is cut through by the river Kajyrty (in its upper course also called Song-Köl) that flows into the Naryn.

The ice on Song-Köl begins to thaw in the middle or at the end of April, and completely disappears by late May.
