"The Screwfly Solution" is a 1977 science fiction short story by Raccoona Sheldon, a pen name for American psychologist Alice Sheldon, who was better known by her other nom de plume James Tiptree Jr. When the story was first published in June 1977, the identity of Alice Sheldon as both Tiptree and "Raccoona" Sheldon was unknown to the public or anyone in the science fiction community; a series of events triggered by the death of Sheldon's mother Mary Hastings Bradley in October 1977 resulted in the identity behind the pen-names being revealed by the end of the same year.
