Jean-Luc Marion (born 3 July 1946) is a postmodern philosopher and a former student of Jacques Derrida. Marion's take on the postmodern is informed by patristic and mystical theology, phenomenology, and modern philosophy. Although much of his academic work has dealt with Descartes and phenomenologists like Martin Heidegger and Edmund Husserl, it is rather his explicitly religious works that have garnered much recent attention. God Without Being, for example, is concerned predominantly with an analysis of idolatry, a theme strongly linked in Marion's work with love and the gift, which is a concept also explored at length by Derrida.

Marion was born in Meudon, Hauts-de-Seine. Marion studied at the University of Nanterre (now the University Paris Ouest Nanterre La Défense) and the Sorbonne and then did graduate work in philosophy from the École Normale Supérieure in Paris, where he studied with Jacques Derrida and Louis Althusser. At the same time, Marion's deep interest in theology was privately cultivated under the personal influence of theologians such as Louis Bouyer, Jean Daniélou, Henri de Lubac, and Hans Urs von Balthasar. After receiving his doctorate in 1980, he began teaching at the University of Poitiers.
