The Amazing Meeting (TAM), stylized as The Amaz!ng Meeting, was an annual conference that focused on science, skepticism, and critical thinking; it was held for twelve years. The conference started in 2003 and was sponsored by the James Randi Educational Foundation (JREF). Perennial speakers included Penn & Teller, Phil Plait, Michael Shermer and James "The Amazing" Randi. Speakers at the four-day conference were selected from a variety of disciplines including scientific educators, magicians, and community activists. Outside the plenary sessions the conference included workshops, additional panel discussions, music and magic performances and live taping of podcasts including The Skeptics' Guide to the Universe. The final Amazing Meeting was held in July 2015.

TAM was first held in 2003, attracting around 150 attendees. When the CSICOP conferences entered a seven-year hiatus in 2005, TAM quickly filled the gap and, with more than 1,000 attendees, developed to become the largest U.S. skeptical conference.

The Skeptics Society and the Committee for Skeptical Inquiry were co-sponsors of the event, providing both financial and promotional support.

People attended the conference for a variety of reasons. The Daily Beast reported that some saw themselves "as waging a broad, multifront battle to drag American culture, inch by inch, away from the nonscientific and the nonlogical". While the organizer of TAM London, Tracy King, said "People come to TAM because they want to learn and hear from leading speakers on subjects which interest them, but they want to have a good time doing it. Our mix of academics, comedians and writers ensures an incredible event where the public can meet like-minded people without feeling like being into science or geek stuff makes them a minority." Magicians were also given a central role at the conference.

The magazine The Skeptic from the Australian Skeptics gave a detailed account of all lectures from the 2010 OZ event.

Randi retired from active participation in the JREF in early 2015; a final TAM was organized in his honour in July 2015. After this, the Committee for Skeptical Inquiry chose Las Vegas as the location for CSICon 2016 to fill the void.

At The Amazing Meeting in 2011 (TAM 9) the Independent Investigations Group (IIG) organised a tribute to James Randi. The group gathered together with other attendees, put on fake white beards, and posed for a large group photo with Randi. At the CSICon in 2017, in absence of Randi, the IIG organised another group photo with leftover beards from the 2011 photo. After Randi was sent the photo, he replied, "I'm always very touched by any such expression. This is certainly no exception. You have my sincere gratitude. I suspect, however that a couple of those beards were fake. But I'm in a forgiving mood at the moment. I'm frankly very touched. I'll see you at the next CSICon. Thank you all."

Beginning in 2009, the Amazing Meeting also hosted a public test of The One Million Dollar Paranormal Challenge for the performance of any paranormal, occult or supernatural event, under proper observing conditions. At The Amazing Meeting 7, it was announced that the $1 Million Challenge prize would not expire in 2010 as previously announced.
