The University of Montpellier (French: Université de Montpellier) is a French public research university in Montpellier in south-east of France. Established in 1220, the University of Montpellier is one of the oldest universities in the world.

The university was split into three universities (the University of Montpellier 1, the University of Montpellier 2 and the Paul Valéry University Montpellier 3) for 45 years from 1970 until 2015 when it was subsequently reunified by the merger of the two former, with the latter, now named Paul Valéry University, Montpellier III remaining a separate entity.
