Revolução sem sangue (lit. Revolution without blood) is a 2024 Portuguese film directed by Rui Pedro Sousa. The film, the director's debut feature, was released on April 11, 2024, in Portugal so as to coincide with the 50th anniversary of the Carnation Revolution, which it depicts. Despite that revolution being largely considered a "bloodless" one, the film focuses on four persons who were killed during the events. That is why the title, after being shown as Revolução sem sangue in the opening credits is stylised Revolução sem sangue (Revolution without blood) in the end credits (which is rendered as Revolução (sem) sangue in certain media).

The film is based on real events that took place on April 24–26, 1974, in Lisbon.
