The Siamese revolution of 1932 or Siamese coup d'état of 1932 (Thai: การปฏิวัติสยาม พ.ศ. 2475 or การเปลี่ยนแปลงการปกครองสยาม พ.ศ. 2475) was a coup d'état by the People's Party which occurred in Siam on 24 June 1932. It ended Siam's centuries-long absolute monarchy rule under the Chakri dynasty and resulted in a bloodless transition of Siam into a constitutional monarchy, the introduction of democracy and the first constitution, and the creation of the National Assembly. Dissatisfaction caused by the economic crisis, the lack of a competent government, and the rise of Western-educated commoners fueled the revolution.

King Prajadhipok remained on the throne and compromised with Khana Ratsadon. Two coups occurred a year later, in April and June amid infighting within the government over Pridi Banomyong's socialist economic plan and a rebellion of the royalists.
