John Colin Wallace (born June 1943) is a British former member of Army Intelligence in Northern Ireland and a psychological warfare specialist. He refused to become involved in the Intelligence-led 'Clockwork Orange' project, which was an attempt to smear various individuals including a number of senior British politicians in the early 1970s. He also attempted to draw public attention to the Kincora Boys' Home sexual abuse scandal several years before the Royal Ulster Constabulary finally intervened.
