Otfrid von Hanstein (1869–1959) was a German actor and writer.
As a novelist, he was prolific in various genres; his best-known works in English-language translation are science fiction novels published in various magazines by Hugo Gernsback.
John Clute describes von Hanstein's science fiction as "technophilic and space-oriented, crude but competent".
[1] E. F. Bleiler reports that his SF novels were suppressed by the Nazi government.
