The Cité Internationale Universitaire de Paris (48°49′16″N 2°20′17″E / 48.82111°N 2.33806°E / 48.82111; 2.33806), also known under its abbreviation of CIUP or often as Cité U (pronounced si-teh-y) among Parisiens, is a private park and foundation located in Paris, France. Since 1925, it has provided general and public services, including the maintenance of several dozen residences for students and visiting academics in the Île-de-France region, and has been officially recognized as a foundation of public interest since then.

Several structures have been designed by architects of note, such as Le Corbusier, Willem Marinus Dudok, Heydar Ghiai and Claude Parent. The residences are organized mostly by nationality, although residents in each maison are not necessarily from the country implied by the naming of the building. Students of 132 different nationalities were living in the Cité Internationale in 2006.

The CIUP is bounded to the south by the Boulevard Périphérique, a busy highway that circles the border of Paris, and to the North by the Parc Montsouris.
