Joseph Fourier University (UJF, French: Université Joseph Fourier, also known as Grenoble I) was a French university situated in the city of Grenoble and focused on the fields of sciences, technologies and health.

[2] The origins of this scientific university can be traced all the way back to 1811 when the scientist Joseph Fourier established a faculty of science in Grenoble.

Part of the university is the Observatoire des Sciences de l'Univers de Grenoble (OSUG), a leading institution in the field of earth, space and environmental sciences.

[3] The main facilities are located on a vast campus east of Grenoble, on the commune of Saint-Martin d'Hères (and partially on that of Gières).

The university runs many laboratories, many in association with CNRS, Grenoble-INP and other major institutions.
