Chernoye, Protected lake in eastern Moscow, Russia.

Chernoye is a lake in the Kosino-Ukhtomsky district of eastern Moscow, part of the Kosino Lakes system. It has two parts: an oval northern stretch 360 m long and 200 m wide, and a triangular southern section 440 m by 430 m created by peat extraction in the first half of the 20th century. Its dark, peat-stained water is less than 3 m deep, with a dry sandy southern shore and a northern bank of birch, willow and aspen.

The Kosino lakes were first mentioned in the early 15th century. In 1923 the Kosino biological station, founded in 1908, helped establish a 54.4-hectare reserve that included Chernoye. A peat quarry opened on its shore in 1942, enlarging the lake, and since 2006 it has formed part of the Kosinsky nature and history park.

The lake's name comes from its dark, peat-stained water, opaque and bordered by boggy shores. In 1985 a nature protection club, "Ekopolis-Kosino", was founded at Kosino; in March 1994, through its cooperation with the Italian UNESCO ecology club "Padua", the Kosino territory was entered on a list of world treasures, a status later lost. Ornithological, botanical, geological and hydrological studies continue on the surrounding land.

Visitors can reach the lake easily by public transportation from downtown Moscow, with several bus routes stopping nearby. The walkable shoreline offers access to different viewing points along the water's edge.

The lake's northern pool is the historic Chernoye, an oval 360 m long and 200 m wide; the triangular southern part appeared in the first half of the 20th century from peat extraction on a neighbouring bog. The two are joined by a short channel, and a boggy channel links the lake to White Lake.
