State of Siege (French: État de siège) is a 1972 French–Italian–West German political thriller film directed by Costa-Gavras starring Yves Montand and Renato Salvatori.

In a flashback which takes up almost the entire film, State of Siege tells of his kidnapping by the Tupamaro guerrilla group, whose members confront him with his involvement in the training of the Uruguayan police, including interrogation techniques and torture to be used on opponents of the authoritarian regime.

Costa-Gavras, living in Paris at the time and preparing his film The Confession, had learned of Mitrione's case in French newspaper Le Monde and decided to make further investigations in Uruguay himself, accompanied by screenwriter Franco Solinas (The Battle of Algiers).
