Paris Diderot University - Paris 7, also known as Université Paris Diderot - Paris 7, is a leading French University located in Paris, France. It is one of the heirs of the Faculty of Sciences of the University of Paris (together with Paris 6), which, founded in the mid-12th century, was one of the earliest universities established in Europe. It adopted its current name in 1994.

Featuring two Nobel Prize laureates, a Fields Medal winner and two former French Ministers of Education among its faculty or former faculty, the University is famous for its teaching in science, especially in mathematics. Indeed many fundamental results of the theory of Probability have been discovered at one of its research centers, the Laboratoire de Probabilités et Modèles Aléatoires (Laboratory of Probability and Random Models). The university is also known for its teaching in psychology, which adopts a specific approach drawing from both the domains of psychopathology and psychoanalysis.

But the University also hosts many others disciplines: currently, there are 2300 educators and researchers, 1100 administrative personnel and 26,000 students studying humanities, science, and medicine.
