Jean Rey was a Belgian Liberal politician who served as the second president of the European Commission from 1967 to 1970. He served as European Commissioner for External Relations from 1958 to 1967. The 1983–1984 academic year at the College of Europe was named in his honour.

The president of the European Commission is the head of the European Commission, the executive branch of the European Union (EU). The president of the Commission leads a cabinet of Commissioners, referred to as the College. The president is empowered to allocate portfolios among, reshuffle, or dismiss Commissioners as necessary. The College directs the commission's civil service, sets the policy agenda and determines the legislative proposals it produces. The commission is the only body that can propose or draft bills to become EU laws.
