Salvator P. Cupcea (also known as Salvador Cupcea; August 8, 1908 – 1958) was a Romanian psychologist, physician, and political figure. From beginnings as a researcher for the Victor Babeș University of Cluj, alongside his friend Alexandru Roșca, he became noted as a pioneer of experimental psychology and psychoanalysis, studying in particular the social marginals. He later immersed himself in the social hygiene and eugenics movement, also specializing in genetic medicine, biological anthropology, and criminology. A collaborator of Iuliu Moldovan, he taught classes at the latter's Institute for much of World War II, when he focused on studying the intelligence of various body types.
During those years, Cupcea flirted with fascism, and endorsed a biopolitical "national hygiene" program. In 1944, he reemerged as a supporter of the Romanian Communist Party and liberal eugenics, serving as Health Minister and representative to the World Health Organization. A founder of the Cluj Medical University and administrator of its Psychiatric Clinic, his final work was in human ecology, food science, and cardiology.
