The École normale supérieure Paris-Saclay (French pronunciation:); also known as ENS Paris-Saclay or Normale Sup' Saclay or ENS Cachan, is a grande école and a constituent member of Paris-Saclay University. It was established in 1892. It is located in Gif-sur-Yvette within the Essonnedepartment near Paris, Île-de-France, France.

ENS Paris-Saclay is one of the most prestigious and selective French grandes écoles. Like all other grandes écoles, this elite higher education institution is not included in the mainstream framework of the French public universities. Along with the École normale supérieure (Paris), ENS Lyon and ENS Rennes, the school belongs to the informal network of French écoles normales supérieures, forming one of the highest level of research and education in the French higher educational system.

In 2014, ENS Paris-Saclay became a founding member of the Paris-Saclay University, an initiative to integrate and combine resources from a number of different grandes écoles, public universities, and research institutions.

The school moved in 2019 to the Saclay campus located in the commune of Gif-sur-Yvette on the Saclay plateau, France's "Silicon Valley," where it will be near other members of the Paris-Saclayresearch-intensive and business cluster.
