The Book of the Damned was the first published nonfiction work by American author Charles Fort. Concerning various types of anomalous phenomena including UFOs, strange falls of both organic and inorganic materials from the sky, odd weather patterns, the possible existence of creatures generally believed to be mythological, disappearances of people, and many other phenomena, the book is considered to be the first of the specific topic of anomalistics.

Charles Hoy Fort (1874–1932) was an American writer and researcher who specialized in anomalous phenomena. The terms "Fortean" and "Forteana" are sometimes used to characterize various such phenomena. His work continues to inspire admirers, who refer to themselves as "Forteans", and has influenced some aspects of science fiction.
