The Vrije Universiteit Brussel (VUB) listen (help·info) (English: Free University of Brussels) is a Dutch and English-speaking research university located in Brussels, Belgium. It has four campuses: Brussels Humanities, Science and Engineering Campus (in Elsene), Brussels Health Campus (in Jette), Brussels Technology Campus (in Anderlecht) and Brussels Photonics Campus (in Gooik).

The Vrije Universiteit Brussel was formed by the splitting in 1970 of the Free University of Brussels, which was founded in 1834 by the Flemish-Brussels lawyer Pierre-Théodore Verhaegen. He wanted to establish a university independent from state and church, where academic freedom would be prevalent. This is today still reflected in the university's motto Scientia vincere tenebras, or Conquering darkness by science, and in its more recent slogan Redelijk eigenzinnig (in Dutch), or Reasonably opinionated. Accordingly, the university is pluralistic – it is open to all students on the basis of equality regardless of their ideological, political, cultural or social background – and it is managed using democratic structures, which means that all members – from students to faculty – participate in the decision-making processes.
