Bogdan Zakharovich Kobulov (Russian: Богда́н Заха́рович Кобу́лов; 1 March 1904 – 23 December 1953) served as a senior member of the Soviet security- and police-apparatus during the rule of Joseph Stalin.

He joined Cheka in 1922, and held minor posts, until he was spotted by Beria in 1931 and recruited to the Secret Political department of the OGPU in Georgia.

[6] After 1945, he was transferred to the Ministry of Foreign Trade, but was brought back to the security organs as First Deputy Minister of Internal Affairs, under Beria, after the death of Stalin in March 1953.

The young physicist Yakov Terletsky remembers seeing the "egg-shaped" Kobulov in an anteroom to Beria's office at Lubyanka in 1945 and estimated his weight at above 400 pounds (180 kg).

[7] When Beria fell from power, Kobulov was arrested along with his boss on 27 June 1953; he was convicted on multiple charges, including espionage, and sentenced to death and executed on 23 December 1953.
