Jean Daujat (Paris, 27 October 1906 – 31 May 1998) was a French philosopher of neo-Thomism, a disciple of Jacques Maritain, and the founder of the Centre d'études religieuses, the Center for Religious Studies, specializing in teaching Christian doctrine.

Classmates included Étienne Borne and Merleau-Ponty in the literature department, the mathematician Chevalley, and the physicist and geneticist Rosenfeld Heir.

Other influential men who attended alongside Daujat were Raymond Aron, Paul Nizan, Jean-Paul Sartre, Henri Cartan and Jean Dieudonné, two of the founders of the Bourbaki group, Louis Neel, Nobel Prize laureate in physics, Olivier Lacombe, also a disciple of Jacques Maritain and specialist in Oriental languages, Henri-Irénée Marrou, Maurice Bardeche, Robert Brasillach, Thierry Maulnier and Simone Weil.

In addition to its own articles and those of Yvonne Estienne, there were many prestigious authors who wrote for the magazine, such as Father Garrigou-Lagrange, Mgt Ghika, Father Lallement, Jacques Maritain, Henri Gheon, Charles Du Bos, Stanislas Broth, Robert of Harcourt, Gustave Thibon, Henriette Charasson, Olivier Lacombe, Merleau-Ponty, and Jacques Madaule.

In December 1946, he defended a thesis on the history of science on the theory of electric and magnetic phenomena before a jury that included Gaston Bachelard and Louis de Broglie.

Because of a Communist threat he received after publishing a booklet showing the perversion of communism, which sold hundreds of thousands of copies, Daujat was asked to speak at numerous conferences on this subject.
