Heinz Neumeyer is a German amateur historian. He specializes in the history of Pomerania and Prussia.
He is associated with the League of Expellees. His views on Polish-German relations have been criticized as biased; for example he claimed that Poland was more responsible than Nazi Germany for starting World War II. Edmund Spevack, a Harvard lecturer on history and literature noted in East European Quarterly that Neumayer represents at best a trend of amateurish German nationalistic writing, and at worst fits in tradition of biased, emotion-driven Nazi-era historiography, and does not deserve to be seen as a reliable scholar. Similarly, Karin Friedrich in The Slavonic and East European Review said that Neumeyer's writing is too emotional for a scholar, uses "the language of national prejudice and anachronistic references", and contains numerous factual errors.
