The Revolution of 1934 (Spanish: Revolución de 1934), also known as the Revolution of October 1934 or the Revolutionary General Strike of 1934, was an uprising during the "black biennium" of the Second Spanish Republic between 5 and 19 October 1934.

The Revolution of 1934 was triggered by anxiety of the Spanish political left after the 1933 general election and entry of the Spanish Confederation of the Autonomous Right (CEDA) into the Spanish government in September 1934. Most of the events occurred in Catalonia and Asturias, and were supported by many Spanish Socialist Workers' Party (PSOE) and General Union of Workers (UGT) members, notably Largo Caballero, as well as members of the National Confederation of Workers (CNT). The uprisings were repressed by Spanish government forces and defeated within two weeks.

Around 2,000 people were killed during the Revolution of 1934 in the initial uprisings and their suppression. Historians have argued that the incident sharpened antagonism between the political right and left in Spain, and was part of the reason for the later Spanish Civil War.
