Jules Régis Debray (; born 2 September 1940) is a French philosopher, journalist, former government official and academic. He is known for his theorization of mediology, a critical theory of the long-term transmission of cultural meaning in human society, and for associating with Marxist revolutionary Che Guevara in Bolivia in 1967 and advancing Salvador Allende's presidency in Chile in the early 1970s. He returned to France in 1973 and later held various official posts in the French government.

During the late 1960s he was a professor of philosophy at the University of Havana in Cuba, and became an associate of Che Guevara in Bolivia. He wrote the book Revolution in the Revolution?, which analysed the tactical and strategic doctrines then prevailing among militant socialist movements in Latin America, and acted as a handbook for guerrilla warfare that supplemented Guevara's own manual concerning the topic.
