The 28 May 1926 coup d'état, sometimes called 28 May Revolution or, during the period of the authoritarian Estado Novo (English: New State), the National Revolution (Portuguese: Revolução Nacional), was a military coup of a nationalist origin, that put an end to the unstable Portuguese First Republic and initiated the Ditadura Nacional (National Dictatorship), later refashioned into the Estado Novo, an authoritarian dictatorship that would last until the Carnation Revolution in 1974.

The chronic political instability and government's neglect of the army created opportunities for military plots. Already in 1925 there were two failed coup attempts on April 18 and July 19. The plotters were acquitted by military court. During winter of 1925 and spring 1926 a group of junior officers planned a new coup and were looking for a senior officer to be the figurehead of their movement. They decided on General Manuel Gomes da Costa, who agreed to join the plotters on May 25.

The revolution started in Braga, commanded by General Manuel Gomes da Costa, followed immediately in Porto, Lisbon, Évora, Coimbra and Santarém. The revolution triumphed when General Gomes da Costa marched on Lisbon along with 15,000 men, being acclaimed by the people of the city.
