Harry Victor Jaffa (October 7, 1918 – January 10, 2015) was an American political philosopher, historian, columnist, and professor. He was a professor emeritus at Claremont McKenna College and Claremont Graduate University, and a distinguished fellow of the Claremont Institute. Robert P. Kraynak says his "life work was to develop an American application of Leo Strauss's revival of natural-right philosophy against the relativism and nihilism of our times".
