Marc Angenot (born Brussels, 1941) is a Belgian-Canadian social theorist, historian of ideas and literary critic.
His dissertation on the rhetoric of surrealism placed him in the line of Chaïm Perelman, and the Groupe Mu of the University of Liège.
He favoured the discourse concept over the structuralist position on "text", of Gérard Genette and Tzvetan Todorov.
His proposal to study the whole array of "social discourse" in a given state of society (1889: Un état du discours social, 1989) was a vast interdisciplinary project concerning the interdiscursive construction of society.
He has been concerned with the nineteenth century, and representative thinkers around revolution and social struggles: Auguste Comte, Saint-Simon, Charles Fourier, Étienne Cabet, Pierre Leroux, Proudhon, the Belgian Hippolyte Colins, Jules Guesde, Georges Sorel, and others.
