Heinrich Klüver (/ˈkluːvər/; May 25, 1897 – February 8, 1979) was a German-American biological psychologist and philosopher born in Holstein.

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 among others the Klüver–Bucy syndrome.

He coined the term "cobweb figure" in the 1920s to describe one of the four form constant geometric visual hallucinations experienced in the early stage of a mescaline trip: "Colored threads running together in a revolving center, the whole similar to a cobweb".
