The Orgburo (Russian: Оргбюро́), also known as the Organisational Bureau (Russian: организационное бюро), of the Central Committee of the Communist Party of the Soviet Union existed from 1919 to 1952, when it was abolished at the 19th Congress of the Communist Party and its functions were transferred to the enlarged Secretariat.

[1] The Orgburo was established during Lenin's government to make important decisions about organisational work in the Soviet Union.

[1] In the same manner as the Politburo and the Secretariat, the Orgburo was elected at plenary sessions of the Central Committee.

The first Orgburo of three members (Vladimirsky, Krestinsky and Sverdlov) was elected on 16 January 1919, at the Central Committee meeting.

Some key Communist politicians (such as Joseph Stalin, Vyacheslav Molotov, Lazar Kaganovich and others) served as members both of the Orgburo and of the Politburo, but most of the Orgburo members were less important figures than those elected to the Politburo and the Secretariat.
