Lake Oron (Russian: озеро Орон, romanized: Ozero Oron) is a lake in eastern Irkutsk Oblast (Bodaybinsky District), Russia.

It is located in the Kodar Mountains, to the south of the southern slopes of the Delyun-Uran Range.

[1] Lake Oron is connected to the Vitim River via a short waterway.

[3] Lake Oron sits at an elevation of 353 meters (1,158 ft) above sea level.

The presence of deep faults beneath Lake Oron strongly suggest that the lake has a tectonic origin, with a hydrological regime determined more by changes in precipitation than by glacier meltwater.
