Finnlands Lebensraum is a 1941 Finnish propaganda book which was published to support the Greater Finland ideology. It was written by geographer Väinö Auer, historian Eino Jutikkala and ethnographer Kustaa Vilkuna who worked for the Finland's state propaganda and information department. National Socialist ideas were later added to the script by Yrjö von Grönhagen, a Nazi-minded Finnish military attaché in Berlin.
