Yeravna-Khorga Lake System (Russian: Еравно-Хоргинской системы озёр) is a group of relatively shallow fresh water bodies in the Yeravninsky District, Buryatia, Russia.

The villages of Isinga, Khorga, Tuldun, Gunda, Shiringa, Garam, as well as Sosnovo-Ozerskoye, the district capital, are located near the lakes.

[3] The lake system lies in the Yeravna Depression, at the southern end of the Vitim Plateau.

It includes 6 large lakes and several smaller ones aligned in a roughly NE/SW direction for about 70 km (43 mi).

[5][2] When the water levels are high the Yeravna lakes are connected with each other by intermittent channels.
