École supérieure d'électricité, commonly known as Supélec, was a French graduate school of engineering. It was one of the most prestigious grande écoles in France in the field of electrical engineering, energy and information sciences. In 2015, Supélec merged with École Centrale Paris and became CentraleSupélec, a constituent member of Université Paris-Saclay.

A grande école is a specialized top-level educational institution in France and some other previous French colonies such as Morocco or Tunisia. Grandes écoles are part of an alternative educational system that operates alongside the mainstream French public university system, and take the shape of institutes dedicated to teaching, research and professional training in either pure natural and social sciences, or applied sciences such as engineering, architecture, business administration, or public policy and administration.
