Eupen-Malmedy or Eupen-Malmédy, also known as the East Cantons (German:Ostkantone; French:Cantons de l'Est; Dutch:Oostkantons) within Belgium, is a geographical area and group of cantons in eastern Belgium. It is composed of the former Prussian districts (Kreise in German) of Malmedy and Eupen, together with the Neutral Moresnet. These territories were annexed to Belgium in 1920 by the Versailles Treaty.
