Dean Radin (; born February 29, 1952) investigates phenomena in parapsychology. Following a bachelor and master's degree in electrical engineering and a PhD in educational psychology Radin worked at Bell Labs, as a researcher at Princeton University and the University of Edinburgh, and was a faculty member at University of Nevada, Las Vegas. He then became Chief Scientist at the Institute of Noetic Sciences (IONS) in Petaluma, California, USA, later becoming the president of the Parapsychological Association. He is also co-editor-in-chief of the journal Explore: The Journal of Science and Healing.

Radin's ideas and work have been criticized by scientists and philosophers skeptical of paranormal claims. The review of Radin's first book, The Conscious Universe, that appeared in Nature charged that Radin ignored the known hoaxes in the field, made statistical errors and ignored plausible non-paranormal explanations for parapsychological data.
