The Université catholique de Louvain (also known as the Catholic University of Louvain, the English translation of its French name, and the University of Louvain, its official English name) is Belgium's largest French-speaking university. It is located in Louvain-la-Neuve, which was expressly built to house the university, and Brussels, Charleroi, Mons, Tournai and Namur. Since September 2018, the university has used the branding UCLouvain, replacing the acronym UCL, following a merger with Saint-Louis University, Brussels.
