George Placzek (German: Georg Placzek; September 26, 1905 – October 9, 1955) was a Czech physicist. His work involved a fundamental theory of Raman scattering, molecular spectroscopy in gases and liquids, neutron physics and mathematical physics.

Together with Otto Frisch, he suggested a direct experimental proof of nuclear fission. Together with Niels Bohr and others, he was instrumental in clarifying the role of uranium-235 for the possibility of nuclear chain reaction.
