Dorong (Russian: Доронг) is a body of fresh water in the Bauntovsky District, Buryatia, Russia.

Dorong is a natural monument of Russia because of its landscapes.

It is a deep and elongated lake, bound by steep mountains on both sides.

The Dorong stretches roughly from north to south for 8.5 km (5.3 mi) and has a width of about 1 km (0.62 mi) which remains fairly constant along the length of the lake.

The Tocha river, belonging to the Tsipa basin, enters the lake from the north and flows out of it from the south.
