UNACO (an initialism for the United Nations Anti-Crime Organization) is a fictional agency within the United Nations created by author Alistair MacLean in a series of movie outlines he developed before his death. These outlines were made into full-length novels by numerous authors, most notably Alastair MacNeill. UNACO uses groups of people to form "strike forces". Each strike force has a leader who communicates with UNACO's top commanders. UNACO also works with other agencies around the world.
