Issyk-Kul (Russian: Иссык-Куль) or Ysyk-Köl (Kyrgyz: Ысык-Көл [ɯsɯ́q kʰɵl]; lit. 'Hot Lake') is an endorheic saline lake in the western Tian Shan mountains in eastern Kyrgyzstan—just south of a dividing range separating Kyrgyzstan from Kazakhstan. It is the eighth-deepest lake in the world, the eleventh-largest lake in the world by volume, and the second-largest saline lake. It is located at an elevation of 1,607 metres (5,272 ft), making it the deepest lake whose deepest point is above sea level at 939 metres (3,081 ft). Despite the elevation and low temperatures during winter, it rarely freezes due to its high salinity.

The lake is a Ramsar site of globally significant biodiversity and forms part of the Issyk-Kul Biosphere Reserve.

Issyk-Kul Lake is 182 kilometres (113 mi) long, up to 60 kilometres (37 mi) wide and its surface area is 6,236 square kilometres (2,408 sq mi). It is the second-largest mountain lake in the world behind Lake Titicaca in South America. It is at an altitude of 1,607 metres (5,272 ft) and reaches 668 metres (2,192 ft) in depth.

About 118 rivers and streams flow into the lake; the largest are the Jyrgalang and Tüp. It is fed by springs, including many hot springs and snow melt. The lake has no current outlet, but some hydrologists hypothesize that the lake's water filters deep underground into the Chu River. The bottom of the lake contains the mineral monohydrocalcite: one of the few known lacustrine deposits (read more).
