Council of People's Commissars on War and Navy Affairs (Russian: Совет Народных Комиссаров по Военным и Морским Делам, Soviet Narodnykh Kommissarov po voyenym i morskim dyelam) was the very first military government agency of the Soviet Russia initially named as the Committee on affairs of War and Navy.

The council was created on November 8, 1917 (day after the October Revolution) on the decree of the 2nd All-Russian Congress of Soviets "On creation of the Provisional Workers' and Peasants' Government" which was the name of the Russian Sovnarkom.

The same day (November 9, 1917) Vladimir Antonov-Ovseyenko was placed in charge of the Petrograd Military District replacing at that post Mikhail Artemyevich Muravyov.

Together with Muravyov, Antonov was placed in charge of an expeditionary force to the Southern Russia, while the acting Supreme Commander-in-Chief was General Nikolay Dukhonin.
