University of Versailles Saint-Quentin-en-Yvelines is a French public university created in 1991, located in the department of Yvelines and, since 2002, in Hauts-de-Seine. It is a constituent university of the federal Paris-Saclay University.

Consisting of eight separate campuses, it is mainly located in the cities of Versailles, Saint-Quentin-en-Yvelines, Mantes-en-Yvelines and Vélizy-Villacoublay / Rambouillet. It is one of the five universities of the Academy of Versailles.
It is one of the four universités nouvelles (new universities) inaugurated in the Île-de-France region after the 2000 University project. It has a population of 19,000 students, a staff of 752 people, and 1,389 teachers and researchers, as well as an additional 285 external teachers.
The university teaches courses in the fields of natural science, social science, political science, engineering, technology, and medicine. It also provides interdisciplinary courses covering the relationships across economics, ethics, natural environment and sustainable development.
In 2013-2014, the UVSQ welcomed approximately 9,600 undergraduate, 6,600 graduate and 700 post-graduate students.
The most popular degree courses are law, economics, and management, with almost 6,200 students representing 37% of total enrollment in 2013, followed by science and engineering school (31%).
Overall, more than half of the undergraduate students enrolled every year are female (60%), except for first-year students at Mantes and Vélizy IUT (University Institute of Technology), two-thirds of whom are male.
The social backgrounds of students are on average, more advantageous than the students matriculated in French public universities. Approximately 50% of first-year students come from business and professional families, and globally about four out of five students belong to wealthy and cultivated social classes. The percentage of students coming from low-income families increased from 14% in 1992 to 20-23% in 2013, but remains a minority. This rate, which is common to most selective universities, reflects the population of the region where the UVSQ is located. Two thirds of first-year students come from the Yvelines department (66%), with a significant concentration around Versailles and Saint-Quentin.
The university welcomes an increasing number of international students; in 2010 there were 2,400 enrolled from 72 different countries, making up 13,3% of UVSQ students. Most were enrolled in Ph.D. programs; 45% of all Ph.D. students were from other countries.
