John Russell Fearn (1908–1960) was a British author and one of the first British writers to appear in American pulp science fiction magazines. Always a highly prolific author, he published not only under his own name, but also as Vargo Statten and other pseudonyms including Thornton Ayre, Polton Cross, Geoffrey Armstrong, John Cotton, Dennis Clive, Ephriam Winiki, Astron Del Martia (and others).
