The Spartacist uprising (German: Spartakusaufstand) was an armed uprising that took place in Berlin from 5 to 12 January 1919.

It occurred in connection with the German revolution that broke out just before the end of World War I. The uprising was primarily a power struggle between the supporters of the provisional government led by Friedrich Ebert of the Majority Social Democratic Party of Germany (MSPD), which favored a social democracy, and those who backed the position of the Communist Party of Germany (KPD) led by Karl Liebknecht and Rosa Luxemburg, which wanted to set up a council republic similar to the one established by the Bolsheviks in Russia.
The government's forces were victorious in the fighting.
