Brad Steiger (February 19, 1936 – May 6, 2018) was an American writer of fiction and non-fiction works on the paranormal, spirituality, UFOs, true crime and biographies.

His books sold well to the public but were widely criticized by academics and skeptics for making far-fetched claims without scientific evidence.

[3] With his wife Sherry Hansen Steiger, he was the author of Four-legged Miracles: Heartwarming Tales of Lost Dogs' Journeys Home.

[9] Steiger's books on UFOs, spirituality, and the paranormal have generally sold well, but have been criticized by many academics for spurious content, lack of scientific evidence, and failure to cite sources, among other reasons.

"[10] Sarah Higley gave Steiger's The Werewolf Book a mixed review and concluded "with a definite penchant for the sensational at the expense of the accurate, the casual reader will find much in it informative and entertaining as well.

"[11] Skeptical investigator Joe Nickell considers Steiger an unreliable source and has noted that he "endlessly cranks out books promoting paranormal claims".
