Kuban Black Sea Oblast (Russian: Куба́но-Черномо́рская о́бласть) was an administrative division (an oblast) of the Russian Soviet Federative Socialist Republic which existed in 1920–1924.
When Soviet power was re-established in the region of Kuban in March 1920, the executive power in the region formally belonged to the Provisional Kuban Executive Committee, established on March 18, 1920.
On March 27, 1920, the committee's duties were transferred to the Kuban Oblast Revolutionary Committee, which supervised the territories of Kuban Oblast and Black Sea Governorate.
On March 29, 1920, the committee was renamed "Kuban Black Sea Revolutionary Committee", and as a result of that the joint territory of Kuban Oblast and Black Sea Governorate started to be referred to as "Kuban Black Sea Oblast", after the committee's new name, although no formal decrees establishing a new administrative unit had been passed.
