Georges Jean Franz Köhler (German pronunciation: [ˈʒɔʁʃ ˈkøːlɐ] (listen); 17 April 1946 in Munich – 1 March 1995 in Freiburg im Breisgau) was a German biologist.

Together with César Milstein and Niels Kaj Jerne, Köhler won the Nobel Prize in Physiology or Medicine in 1984, "for work on the immune system and the production of monoclonal antibodies". Milstein and Köhler's technique for producing monoclonal antibodies laid the foundation for the exploitation of antibodies for diagnostics, therapeutics and many other scientific applications.
