John Benjamin Kogut (6 March 1945 in Brooklyn) is an American theoretical physicist, specializing in high energy physics.

Kogut received in 1971 his PhD from Stanford University under James Bjorken with thesis Quantum electrodynamics at infinite momentum: applications to high energy scattering. From 1971 to 1973 he was a visiting scholar at the Institute for Advanced Study and from 1971 to 1977 assistant professor of physics at Cornell University. For 27 years he was on the physics faculty of the Loomis Laboratory at the University of Illinois, Urbana-Champaign, retiring in 2005 as professor emeritus. Since then, he has been a program manager at the United States Department of Energy, Office of Science (SC), Office of High Energy Physics.

Kogut is known for the Kogut-Susskind fermion and his collaboration with Leonard Susskind on the Hamiltonian formulation of Kenneth G. Wilson's lattice gauge theory.[1] He also did research on the "infinite-momentum frame"[2] (the subject of his PhD thesis) and the parton model.

Kogut played a leading role in opposing the Strategic Defense Initiative (aka "Star Wars").[3]

From 1976 to 1978 he was a Sloan Fellow. In 1982 he was elected a Fellow of the American Physical Society. For the academic year 1987–1988 he was a Guggenheim Fellow.
