The All-Union Pioneer Organization named after V. I. Lenin (abbreviation: VPO im. Lenin) was a mass voluntary children's communist organization in the USSR. It was established by the decision of the Second All-Russian Conference of the Russian Communist Youth League, which adopted the resolution "Children's Movement" on May 19, 1922.
