Robert Rutherford "Colonel" McCormick (July 30, 1880 – April 1, 1955) was a member of the McCormick family of  Chicago who became owner and publisher of the Chicago Tribune newspaper. A leading non-interventionist, an opponent of American entry into World War II and of the increase in Federal power brought about by the New Deal, he continued to champion a traditionalist course long after his positions had been eclipsed in the mainstream.
