Nedzheli (Russian: Ниди́ли or Ниджили;[1] Yakut: Нидьили, romanized: Nicili) is a lake in Kobyaysky District, Sakha Republic (Yakutia), Russia.

[1] Nedzheli is located near the Lena, about 60 km (37 mi) —in a straight line— southwest of the village of Sangar.

The crucian carp variety of the Nedzheli is highly appreciated in Yakutia and has been introduced to other lakes in the region.

Siberian cranes, black-headed gulls, river terns, Eurasian teals, ruffs and diving ducks are common in the shores of the lake.

In former times the Nedzheli used to be a breeding place of the common goldeneye, but since the local people began to use motor boats the population declined dramatically.
