Kurt Zadek Lewin or Kurt Tsadek Lewin (/ˈlɪn, ləˈvn/ LOO-in, lə-VEEN; German: [leˈviːn]; 9 September 1890 – 12 February 1947) was a German-American psychologist, known as one of the modern pioneers of social, organizational, and applied psychology in the United States. During his professional career, Lewin's academic research and writings focuses on applied research, action research, and group communication.

Lewin is often recognized as the "founder of social psychology" and was one of the first to study group dynamics and organizational development. A Review of General Psychology survey, published in 2002, ranked Lewin as the 18th-most cited psychologist of the 20th century. During his career, he was affiliated with several U.S. and European universities, including the University of Berlin, Cornell University, MIT, Stanford University, and the University of Iowa.
