The Flag of Siberia (Russian: Флаг Сибири, romanized: Flag Sibiri) is the unofficial flag used to represent the region of Siberia. This flag first became widely used during the Russian Civil War and the short-lived Siberian Republic. After it failed, the flag continued to represent sentiments of Siberian regionalism.
