Raymond Eveleth Fowler, born in Salem, Massachusetts, on November 11, 1933, is an American UFO investigator and author who spent decades documenting sightings and abduction reports across New England. He is best known for The Andreasson Affair (1979), his account of Betty Andreasson's reported 1967 encounter, and The Allagash Abductions (1993), on the four canoeists at the center of the Allagash abduction case in northern Maine.

Fowler graduated magna cum laude from Gordon College in Wenham, Massachusetts, joined the U.S. Air Force in 1952 and served with the USAF Security Service. He then spent 25 years with GTE Government Systems, working as a task manager and senior planner on weapons programs including the Minuteman and MX missiles. In his spare time he investigated sightings for NICAP, chairing its Massachusetts subcommittee, and he was its lead investigator on the 1965 Exeter, New Hampshire sighting, filing an 18-page report. He was an early-warning coordinator for the Air Force-funded University of Colorado UFO study and later director of investigations for MUFON, for which he wrote an early field investigator's manual. J. Allen Hynek called him "an outstanding UFO investigator and fact-finder" in a foreword to his first book, UFOs: Interplanetary Visitors (1974).

The Andreasson case reached Fowler after Betty Andreasson wrote to Hynek in 1975 about events at her South Ashburnham, Massachusetts, home in January 1967. Under hypnotic regression she described beings entering the house and taking her aboard a craft. The Andreasson Affair, published by Prentice-Hall with a foreword by Hynek, presented those sessions and is credited with bringing alleged alien implants into the abduction literature. Two sequels, The Andreasson Affair, Phase Two and The Andreasson Legacy (1997), followed. Critics were blunt: the psychiatrist Ernest Taves wrote in Skeptical Inquirer that as a serious investigation the book was "a failure," and Philip Klass argued that parts of the account were fantasy.

The Allagash investigation began in the late 1980s, when Jim Weiner, one of four art students who had seen a bright light over Eagle Lake in 1976, contacted Fowler about night-time visions. Fowler arranged hypnotic regression sessions in which three of the men described being taken aboard a craft, and Wild Flower Press published his book with an introduction by Budd Hopkins. In 2016 a fourth witness, Chuck Rak, told the Maine newspaper The County that parts of the story were fabricated; Fowler replied that Rak had shown little detailed recall under hypnosis. Fowler also described his own abduction experiences, first in The Watchers (1990) and The Watchers II (1995), both with forewords by Whitley Strieber, and most fully in UFO Testament: Anatomy of an Abductee (2002). He moved to Kennebunk, Maine, in 2002.

Both cases drew fresh attention in 2026, fifty years after the Allagash trip. In May, Weiner and Charlie Foltz retold the Allagash story to Jesse Michels on American Alchemy, and Ryan Sprague's Somewhere in the Skies devoted a June episode to the Allagash case and revisited the Andreasson case in a September classic episode. Filmmaker Nomar Slevik premiered a short documentary about a strange account involving Fowler's father. Fowler's books remain the primary published accounts of both the Andreasson and Allagash cases, which rank among the most widely retold abduction stories in the United States.
