The Revolutionary Communist Party, USA is a new communist party in the United States founded in 1975 and led by its chairman, Bob Avakian. The party organizes for a revolution to overthrow the system of capitalism and replace it with a socialist state, with the final aim of world communism. The RCP is frequently described as a cult around Avakian.

Maoism, also known as Mao Zedong Thought, is a variety of Marxism–Leninism that Mao Zedong developed while trying to realize a socialist revolution in the agricultural, pre-industrial society of the Republic of China and later the People's Republic of China. A difference between Maoism and traditional Marxism–Leninism is that a united front of progressive forces in class society would lead the revolutionary vanguard in pre-industrial societies rather than communist revolutionaries alone. This theory, in which revolutionary praxis is primary and ideological orthodoxy is secondary, represents urban Marxism–Leninism adapted to pre-industrial China. Later theoreticians expanded on the idea that Mao had adapted Marxism–Leninism to Chinese conditions, arguing that he had in fact updated it fundamentally and that Maoism could be applied universally throughout the world. This ideology is often referred to as Marxism–Leninism–Maoism to distinguish it from the original ideas of Mao.
