North Caucasian Soviet Republic (Russian: Се́веро-Кавка́зская Сове́тская Респу́блика, Severo-Kavkazskaya Sovetskaya Respublika; 7 July 1918 – 11 January 1919) was a territory in the North Caucasus established to consolidate Soviet power during the Russian Civil War.

A republic of the Russian SFSR, it was created by merging the Kuban-Black Sea Soviet Republic, the Stavropol Soviet Republic, and the Terek Soviet Republic[1].

Its capital was Yekaterinodar; however, on August 16, 1918 Yekaterinodar was taken by Denikin's Volunteer Army[2], and the capital was moved to Pyatigorsk[3].

By the end of 1918, the majority of the republic's territory was captured by the White Army.

On January 11 1919, the All-Russian Central Executive Committee abolished the republic[4].
