The 1930 coup d'état, also known as the September Revolution by its supporters, involved the overthrow of the Argentine government of Hipólito Yrigoyen by forces loyal to General José Félix Uriburu. The coup took place on 6 September 1930 when Uriburu led a small detachment of troops into the capital, experiencing no substantial opposition and taking control of the Casa Rosada. Large crowds formed in Buenos Aires in support of the coup. Uriburu's forces took control of the capital and arrested Radical Civic Union supporters.

There were no casualties in the coup. Future Argentinean President Juan Perón took part in the coup on the side of Uriburu.

The coup led to the end of constitutional government in Argentina and the establishment of a military dictatorship. Argentine politics would be characterized by considerable political instability (weak democracies, coups, military dictatorships) into the 1980s.
