Paris-Saclay is a research-intensive and business cluster currently under construction in the south of Paris, France. It encompasses research facilities, two French major universities with higher education institutions (grandes écoles) and also research centers of private companies. In 2013, the Technology Review put Paris-Saclay in the top 8 world research clusters. In 2014, it comprised almost 15% of French scientific research capacity. The earliest settlements are from the 1950s, and this area was subsequently extended several times during the 1970s and 2000s. Several projects are underway to continue the development of the campus, including the relocation of some facilities. The area is now home to many of the Europe's largest high-tech corporations, and to the two French universities Paris-Saclay University (CentraleSupélec, ENS Paris-Saclay, Paris-Saclay Faculty of Science, etc.) and the Polytechnic Institute of Paris (École Polytechnique, Telecom Paris, etc.). The Paris-Saclay University was ranked 15th in the world in the 2023 ARWU ranking. It was also placed 1st in the world for Mathematics and 9th in the world for Physics (1st in Europe).The goal was to strengthen the cluster to build an international scientific and technological hub that can compete with other high-technology business districts, such as Silicon Valley or Cambridge, MA. This project started in 2006 and is likely to end in 2022. The main part is the construction of the campus du plateau de Saclay.

Bures-sur-Yvette (French pronunciation: [byʁ syʁ ivɛt] , lit. "Bures-on-Yvette") is a commune in the Essonne department in the Île-de-France region in Northern France. It is a southern Parisian outer suburb in the Vallée de Chevreuse, with a population of 9,254 as of 2021.

Bures-sur-Yvette station is one of the two RER B station of Bures-sur-Yvette, near Paris, in France. This station is used to access University of Paris-Sud, and Institut des Hautes Études Scientifiques.

Paris-Saclay University (French: Université Paris-Saclay) is a combined technological research institute and public research university in Paris, France. Paris-Saclay was established in 2019 after the merger of four technical grandes écoles, as well as several technological institutes, engineering schools, and research facilities; giving it fifteen constituent colleges with over 48,000 students combined.With the merger, the French government has explicitly voiced their wish to rival top American technological research institutes, such as the MIT. The university has over 275 laboratories in particle physics, nuclear physics, astrophysics, atomic physics and molecular physics, condensed matter physics, theoretical physics, electronics, nanoscience and nanotechnology. It is part of the larger Paris-Saclay cluster, which is a research-intensive academic campus encompassing Paris-Saclay University, the Polytechnic Institute of Paris, combined with a business cluster for high-technology corporations. Paris-Saclay notably also includes the Institut des Hautes Études Scientifiques, where many contributions to the development of modern mathematics have been made, amongst them modern algebraic geometry and catastrophe theory.As of 2021, 11 Fields Medalists and 4 Nobel Prize winners have been affiliated with the university and its associated research institutes.

L'Institut national des sciences et techniques nucléaires (INSTN, National Institute for Nuclear Science and Technology), is a public higher education institution administered by the CEA (French Alternative Energies and Atomic Energy Commission) under the joint authority of the Ministry of National Education, Higher Education and Research, the Ministry of the Economy, Industry and the Digital Sector and the Ministry of the Environment, Energy and Marine Affairs. It is the main centre of education for nuclear energy in France.

The Polytechnic Institute of Paris (French: Institut polytechnique de Paris) is a public technological university located in Palaiseau, France. It consists of five engineering grandes écoles: École polytechnique, ENSTA Paris, ENSAE Paris, Télécom Paris and Télécom SudParis. With the Paris-Saclay University, the Polytechnic Institute of Paris is part of the Paris-Saclay project, which is a research-intensive academic campus and business cluster being developed on the Plateau de Saclay near Paris. The project integrates several engineering schools and research centers that are part of the world's top research organizations in various fields.The technological university was formed around the École polytechnique, one of the most respected and selective grandes écoles in France. Among its alumni and teachers are five Nobel prize winners, two Fields medalists, three presidents of France and many CEOs of French and international companies.
