Yeravna-Khorga Lake System () 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.
There are fisheries of local importance in most of the lakes of the group. Geography 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 . The catchment area of the lake system is located in a forest steppe zone.

Hydrography When the water levels are high the Yeravna lakes are connected with each other by intermittent channels. The outlet of the lake area is via the Khorga lakes to the northeast through the Kholoy, a small, shallow tributary of the Vitim River flowing from Isinga lake at the northeastern end.
