"The Magnificent Possession" is a science fiction short story by Isaac Asimov. It was first published in the July 1940 issue of Future Fiction and reprinted in the 1972 collection The Early Asimov. It was the ninth story written by Asimov, and the seventh to be published. The author recalls that the story, an attempt at humour, was embarrassing to read later, and that he was glad that his long-time editor, John W. Campbell, never saw it, as he would certainly have rejected it.
