The White Army or White Guard, also referred to as the Whites or White Guardsmen, was a common collective name for the armed formations of the White movement and anti-Bolshevik governments during the Russian Civil War. They fought against the Red Army of Soviet Russia.

The White movement, also known as the Whites, was a loose confederation of anti-communist forces that fought the communist Bolsheviks, also known as the Reds, in the Russian Civil War (1917–1923) and that to a lesser extent continued operating as militarized associations of rebels both outside and within Russian borders in Siberia until roughly World War II (1939–1945). The movement's military arm was the White Army, also known as the White Guard or White Guardsmen.
