The East Siberian Military District was a Military district of the Russian Empire and the Soviet Union, which existed between 1865—1884, 1920—1923 and 1945—1953. Between 1884-1919, it was known as the Irkutsk Military District.

The East Siberian Military District was originally formed as a military district of the Russian Empire in 1864. It included the territories of the Irkutsk and Yenisei provinces, and Amur, Transbaikal, Primorsk and Yakutsk regions. On July 14, 1884, it was divided into two separate military districts : the Irkutsk Military District and the Amur Military District, which existed until 1919, when the Red Army conquered Siberia.

After the arrival of the Red Army, a new East Siberian Military District of the Red Army was formed on March 15, 1920 on the territory that included the Tomsk, Yenisei, Irkutsk provinces and the Yakutsk region. In January 1923, the district was abolished. The territory and troops were transferred to the Siberian Military District.

On July 9, 1945, the East Siberian Military District was created for the third time, as part of the Irkutsk Region, Krasnoyarsk Territory, the Yakutsk Autonomous Soviet Socialist Republic and the Tuva Autonomous District. On June 30, 1953, the district was disbanded with the transfer of territory and troops to the West Siberian and Zabaikalsky military districts.
