Devil of a State is a 1961 novel by Anthony Burgess based on his experience living and working in Bandar Seri Begawan, the capital of the Southeast Asian sultanate of Brunei, on the island of Borneo, in 1958-59.

It is the fourth of what have been called Burgess's "exotic novels", the others being Time for a Tiger, The Enemy in the Blanket and Beds in the East.

To avoid any risk of a libel suit the action was set in an imaginary caliphate, "Dunia", the location was moved to East Africa, and a UN representative was substituted for the British adviser. In the first volume of his autobiography, Little Wilson and Big God, Being the First Part of the Confessions of Anthony Burgess (1987), Burgess wrote:

This novel was, is, about Brunei, which was renamed Naraka, Malayo-Arabic for hell. Little invention was needed to contrive a large cast of unbelievable characters and a number of interwoven plots. Though completed in 1958, the work was not published until 1961, for what it was worth it was made a choice of the book society. Heinemann, my publisher, was doubtful about publishing it: it might be libelous. I had to change the setting from Borneo to an East African one. Heinemann was right to be timorous. In early 1958 'The Enemy in the Blanket' appeared and this at once provoked a libel suit.
