Reichskommissariat Moskowien (RKM; Russian: Рейхскомиссариат Московия), also spelled as Moskau, literally "Reich Commissariat of Muscovy (or Moscow)", was the civilian occupation regime that Nazi Germany intended to create in central and northern European Russia during World War II, one of several similar Reichskommissariat. It was also known initially as the Reichskommissariat Russland (Reich Commissariat of Russia). Siegfried Kasche was the projected Reichskomissar, but due to the German failure to occupy the territories intended to form the Reichskommissariat, it remained on paper only.
