The World Peace Council (WPC) is an international organization created in 1949 by the Cominform and propped up by the Soviet Union. Throughout the Cold War, WPC engaged in propaganda efforts on behalf of the Soviet Union, whereby it criticized the United States and its allies while defending the Soviet Union's involvement in numerous conflicts.

The organization had the stated goals of advocating for universal disarmament, sovereignty, independence, peaceful co-existence, and campaigns against imperialism, weapons of mass destruction and all forms of discrimination. The organization's propagandizing for the USSR led to the decline of its influence over the peace movement in non-Communist countries.

Its first president was the French physicist and activist Frédéric Joliot-Curie. It was based in Helsinki, Finland, from 1968 to 1999, and since in Athens, Greece.

In August 1948 through the initiative of the Communist Information Bureau (Cominform) a "World Congress of Intellectuals for Peace" was held in Wrocław, Poland.

This gathering established a permanent organisation called the International Liaison Committee of Intellectuals for Peace—a group which joined with another international Communist organisation, the Women's International Democratic Federation to convene a second international conclave in Paris in April 1949, a meeting designated the World Congress of Partisans for Peace (Congrès Mondial des Partisans de la Paix). Some 2,000 delegates from 75 countries were in attendance at this foundation gathering in the French capital.

A new permanent organization emerged from the April 1949 conclave, the World Committee of Partisans for Peace. At a Second World Congress held in Warsaw in November 1950, this group adopted the new name World Peace Council (WPC). The origins of the WPC lay in the Cominform's doctrine that the world was divided between "peace-loving" progressive forces led by the Soviet Union and "warmongering" capitalist countries led by the United States, declaring that peace "should now become the pivot of the entire activity of the Communist Parties", and most western Communist parties followed this policy.

In 1950, Cominform adopted the report of Mikhail Suslov, a senior Soviet official, praising the Partisans for Peace and resolving that, "The Communist and Workers' Parties must utilize all means of struggle to secure a stable and lasting peace, subordinating their entire activity to this" and that "Particular attention should be devoted to drawing into the peace movement trade unions, women's, youth, cooperative, sport, cultural, education, religious and other organizations, and also scientists, writers, journalists, cultural workers, parliamentary and other political and public leaders who act in defense of peace and against war."

Lawrence Wittner, a historian of the post-war peace movement, argues that the Soviet Union devoted great efforts to the promotion of the WPC in the early post-war years because it feared an American attack and American superiority of arms at a time when the US possessed the atom bomb but the Soviet Union had not yet developed it. This was in opposition to the theory that America had no plans to attack anyone, and the purpose of the WPC was to disarm the US and the NATO alliance for a future Soviet attack.
