The Institute of Philosophy is the faculty of philosophy at the KU Leuven in the Belgian city of Leuven. It was founded in 1968 when the Institut supérieur de Philosophie - Hoger Instituut voor Wijsbegeerte of the Catholic University of Leuven (1835–1968) was split into a Dutch-speaking entity and a French-speaking entity. Its main buildings are located in the center of Leuven at the Kardinaal Mercier Square, named for the founder of the original institute.
