ESSEC Business School

The École Supérieure des Sciences Economiques et Commerciales, more commonly known as ESSEC Business School or simply ESSEC, is a business school and grande école based in France. Founded in 1907, its principal campus is located in Cergy in the île-de-France region, but also has locations in La Défense, Rabat, and Singapore.

Founded by Jesuits in response to the creation of HEC Paris, it remained independent of any chamber of commerce and industry before passing it in 1981 under the control of the Versailles, which became the CCI of Paris Île-de-France in 2013. Today, ESSEC is a member of the CY Alliance, formerly the Université Paris-Seine.
