Our Man in Havana (1958) is a novel set in Cuba by the British author Graham Greene. Greene uses the novel to mock intelligence services, especially the British MI6, and their willingness to believe reports from their local informants. The book predates the Cuban Missile Crisis, but certain aspects of the plot, notably the role of missile installations, appear to anticipate the events of 1962.

Henry Graham Greene was an English writer and journalist regarded by many as one of the leading novelists of the 20th century.
