Polish Communist Party (2002)

The Polish Communist Party (Polish: Komunistyczna Partia Polski, KPP), or the Communist Party of Poland, was a Marxist–Leninist communist party in Poland. It was founded in 2002 by former members of the Union of Polish Communists "Proletariat" (Polish: Związek Komunistów Polskich „Proletariat”), a Marxist-Leninist party that functioned between 1990 and 2002, and was ultimately banned in 2002. In 2013, the KPP co-founded the Initiative of Communist and Workers' Parties, and cooperated with minor socialist and left-wing nationalist parties such as the Polish Labour Party, Polish Socialist Party, and the Democratic Party of the Left. The party battled constant attempts at outlawing it; on 3 December 2025, the Constitutional Tribunal declared the party's program to go against the Polish Constitution, and the KPP was formally banned on 30 December 2025.

The party described itself as "a Marxist-Leninist party that draws on the best patriotic and internationalist traditions of the Polish labor movement", and aspired to be the historical and ideological heir of the Communist Party of Poland, Polish Workers' Party and the Polish United Workers' Party. The KPP represented a conservative and nationalist tendency of communism, and upheld the legacy of the Polish People's Republic, including that of the Endo-Communist Mieczysław Moczar. It called for restoration of Polish socialism, based on abolition of classes and private property, and socialization of the economy. It postulated Polish withdrawal from the EU and NATO, supported the Russian Federation in the Russo-Ukrainian War, and supported the post-Maoist People's Republic of China, along with Vietnam, Laos, North Korea and Cuba as socialist states.
