The 18th Orgburo of the All-Union Communist Party (Bolsheviks) was elected by the 1st Plenary Session of the 18th Central Committee, in the immediate aftermath of the 18th Congress. It was the last Orgburo, as its functions were transferred to an enlarged Secretariat at the 19th Congress before the Orgburo itself was abolished.
