The Book of the Damned was the first published nonfiction work by American author Charles Fort (first edition 1919). 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 (August 6, 1874 – May 3, 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. Fort's books sold well and are still in print. His work continues to inspire admirers, who refer to themselves as "Forteans", and has influenced some aspects of science fiction.
