The Federmesser culture or Federmesser group is a tool-making tradition of the late Upper Palaeolithic era, of the Northern European Plain from Poland (where the culture is called Tarnowian and Witowian) to northern France and Britain, dating to between 14,000 and 12,800 years ago. It is closely related to the Tjongerian culture, as both have been suggested as being part of the more generalized Azilian culture.
