Domenico Losurdo (14 November 1941 – 28 June 2018) was an Italian Marxist philosopher and historian better known for his critique of anti-communism, colonialism, imperialism, the European tradition of liberalism and the concept of totalitarianism.

He was director of the Institute of Philosophical and Pedagogical Sciences at the University of Urbino, where he taught history of philosophy as Dean at the Faculty of Educational Sciences. Since 1988, Losurdo was president of the Hegelian International Association Hegel-Marx for Dialectical Thought. He was also a member of the Leibniz Society of Sciences in Berlin (an association in the tradition of Gottfried Wilhelm Leibniz's Prussian Academy of Sciences) as well as director of the Marx XXI political-cultural association.

From communist militancy to the condemnation of American imperialism and the study of the African-American and Native American question, Losurdo was also a participant in national and international politics.
