IESE Business School is the graduate business school of the University of Navarra.

IESE has campuses in Barcelona, Madrid, and New York City and teaching facilities in Munich and Sao Paulo. IESE is an initiative of Opus Dei, a personal prelature of the Catholic Church.

IESE came into prominence in 1964 by launching the first two-year MBA program in Europe under the guidance of the Harvard Business School. The Harvard-IESE Joint Advisory Committee was established in 1963 and continues to meet annually concerning matters of mutual interest.[6] In 2007, IESE began offering academic programs in the United States with the opening of the Institute for Media and Entertainment (IME) in New York City. With the opening of its state-of-the-art New York Center building in midtown Manhattan in April 2010, IESE became the first European business school to establish permanent operations in the U.S.
