Johan Karel de Vree (April 16, 1938 - May 28, 2017) was a Dutch political scientist, and professor Theory of International Relations at Utrecht University,^[2] known for his "scientists" approach to political science.^[3]

De Vree started the Geodesy study in 1959 at the Delft University of Technology. The next year in 1960 he moved to University of Amsterdam, where he obtained his MA in political and social sciences in 1967. He continued his graduate study and obtained his PhD in 1972 under Hans Daudt with the thesis Political integration: the formation of theory and its problems.^[2]

After his graduation in 1967 De Vree started his academic career as lecturer at the Europa Institute of the University of Amsterdam. In 1973 he was appointed Professor Theory of International Relations at the Utrecht University, where he retired in 1999.^[2] De Vree was na active member of the Dutch Political Science Association, where he was president from 1975 to 1983. He was also a member of the American Association for the Advancement of Science and of the New York Academy of Sciences.

De Vree is particularly known for the comprehensive formal theory of human behavior, that he had built on throughout his career. He felt related to the theoretical physicists, who strived for a theory of everything. He is looking for the systems that underlay human behavior. This approach he thought would eventually lead to "a kind of socio-political weather forecast".^[1]
