The Freundeskreis der Wirtschaft, or Circle of Friends of the Economy (which became known as "Freundeskreis Reichsführer SS", "Freundeskreis Himmler" or "Keppler Circle") was a group of German industrialists whose aim was to strengthen the ties between the Nazi Party and business and industry. The group was formed and co-ordinated by Wilhelm Keppler, one of Adolf Hitler's close economic advisors.
