The State Flag of the Union of Soviet Socialist Republics, or simply the Soviet flag, was a red banner with two communist symbols displayed in the canton: a gold hammer and sickle topped off by a red five-point star bordered in gold. The flag's design and symbolism are derived from several sources, but emerged during the Russian Revolution. It has also come to serve as the standard symbol representing communism as a whole, recognized as such in international circles, even after the dissolution of the Soviet Union in 1991.

In politics, a red flag is predominantly a symbol of left-wing politics, including socialism, communism, Marxism, labour movement, and anarchism. The originally empty or plain red flag has been associated with left-wing politics since the French Revolution (1789–1799).
