Heinrich Klüver (; May 25, 1897 – February 8, 1979) was a German and American psychologist born in Holstein.
After having served in the Imperial Germany Army during World War I, he studied at both the University of Hamburg and the University of Berlin from 1920-23. In the latter year, he arrived in the United States to attend Stanford University. He received his Ph.D. in physiological psychology from Stanford University. In 1927 he married Cessa Feyerabend and settled in the United States permanently, becoming a naturalized U.S. citizen in 1934. Klüver was a member of the 'core group' of cybernetics pioneers that participated in the Macy Conferences of the 1940s and 1950s. He collaborated most often and fruitfully with Paul Bucy and made various contributions to neuroanatomy throughout his career. His expositions of and experiments with mescaline were also groundbreaking at the time.
