The James Randi Educational Foundation (JREF) is an American grant-making institution founded in 1996 by magician and skeptic James Randi. As a nonprofit organization, the mission of JREF includes educating the public and the media on the dangers of accepting unproven claims, and to support research into paranormal claims in controlled scientific experimental conditions. The organization announced its change to a grant-making foundation in September 2015.

The organization previously administered the One Million Dollar Paranormal Challenge, a prize of one million U.S. dollars to anyone who could demonstrate a supernatural or paranormal ability under agreed-upon scientific testing criteria.

The organization has been funded through member contributions, grants, and conferences, though it ceased accepting memberships after 2015. For several years, the JREF website published the blog Swift, which included news and information as well as exposés of paranormal claimants.

The James Randi Educational Foundation (JREF) officially came into existence on February 29, 1996, when it was registered as a nonprofit corporation in the State of Delaware in the United States. On April 3, 1996, James Randi formally announced the creation of JREF through his email hotline.

THE FOUNDATION IS IN BUSINESS! It is my great pleasure to announce the creation of the James Randi Educational Foundation. This is a non-profit, tax-exempt, educational foundation under Section 501(c)3 of the Internal Revenue Code, incorporated in the State of Delaware. The Foundation is generously funded by a sponsor in Washington D.C. who wishes, at this point in time, to remain anonymous.

Randi stated that Johnny Carson was a major sponsor, giving several six-figure donations.
