The Patom Highlands (Russian: Патомское нагорье)[1] are a mountainous area in Eastern Siberia, Russia.

Administratively most of the territory of the uplands is part of Irkutsk Oblast, with a smaller section in northern Zabaykalsky Krai.

Besides these two towns, other inhabited localities of the mountain region are: Mama, Perevoz, Kropotkin, Svetly and Bolshoy Patom, Bodaybinsky District.

The incident provoked wide outrage across pre-revolutionary Russia when Alexander Kerensky reported it in the Duma.

The highest point is a 1,924 metres (6,312 ft) high unnamed summit located at 57°39′8″N 117°47′19″E / 57.65222°N 117.78861°E / 57.65222; 117.78861 in the southeastern end, southeast of Lake Nichatka in Zabaykalsky Krai.
