Harold James Nicholson (born 1950) is a former Central Intelligence Agency officer and a twice-convicted spy for Russia's Foreign Intelligence Service (SVR). His recruitment to the SVR appears to have occurred in the wake of a much publicized arrest of senior CIA officer and Moscow mole Aldrich Ames in February 1994, which, in the words of CIA veteran and author Tennent Bagley, had "exposed extraordinary slackness of CIA security procedures."
