Ghost Stories (magazine): Ghost Stories was a U.S. pulp magazine that published 64 issues between 1926 and 1932.

It was a companion magazine to "True Story" and "True Detective Stories", and focused almost entirely on stories about ghosts, many of which were written by staff writers but presented under pseudonyms as true confessions.  These were often accompanied by faked photographs to make the stories appear more believable.  "Ghost Stories" also ran original and reprinted contributions, including works by Robert E. Howard, Carl Jacobi, and Frank Belknap Long.  Among the reprints were Agatha Christie's "The Last Seance" (under the title "The Woman Who Stole a Ghost"), several stories by H.G. Wells, and Charles Dickens' "The Signal-Man".  The magazine was initially successful, but began to lose readers, and in 1930 was sold to Harold Hersey.
