The "Four Policemen" was a postwar council with the Big Four that US President Franklin Roosevelt proposed as a guarantor of world peace. Their members were called the Four Powers during World War II and were the four major Allies of World War II: the United Kingdom, the United States, the Soviet Union, and China. Roosevelt repeatedly used the term "Four Policemen" starting in 1942.

The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – United Kingdom, United States, Soviet Union, and China.
