Željko Ražnatović (, ; 17 April 1952 – 15 January 2000), known as Arkan (Аркан), was a Serbian career criminal and commander of a paramilitary force in the Yugoslav Wars, called the Serb Volunteer Guard. He was on Interpol's most wanted list in the 1970s and 1980s for robberies and murders committed in a number of countries across Europe. He was later indicted by the UN for crimes against humanity for his role during the wars. Arkan was assassinated in 2000 before his trial.
