Taner Edis (born August 20, 1967) is a Turkish American physicist and skeptic. He is a professor of physics at Truman State University. He received his B.S. from Boğaziçi University in Turkey and his M.A. and Ph.D. from Johns Hopkins University. Edis is the author of several books on creationism, religion and science. He is a fellow for the Committee for Skeptical Inquiry.

Born in Istanbul, Turkey to secular Turkish and American parents, Edis traveled to the United States many times in his childhood.

Edis has lived in the United States since starting his master's degree at Johns Hopkins University. He earned his Ph.D. in 1994. He first encountered creationism during his studies in America – he thought it an "American oddity".

Edis is professor of physics at Truman State University. He became a fellow for Committee for Skeptical Inquiry in 2022.

Edis's research "focuses on paranormal and supernatural claims and explores what their failures say about the nature of science". He is particularly interested in Islamic creationism and the American intelligent design movement. Edis has been called "a liberal atheist, secular humanist and a zealous proselyte of scientific reason".

Fascinated by the plethora of supernatural and fringe science beliefs around him, and concerned about the rise of Islamist politics back in Turkey, Edis first got involved with skeptical inquiry into religious and paranormal claims during his graduate studies. "Science is difficult," states Edis to Point of Inquiry interviewer D.J. Grothe in answer to a question about why science has not replaced religion. Edis explains to his students that they will have difficulty understanding this "because the human brain is not wired to understand something like quantum mechanics and neutrinos correctly, it's a struggle." In an interview with Susan Gerbic at CSICon, Edis characterized his more recent writings on the subjects of science and skepticism by saying that "it might [even] be rational to believe in certain falsehoods. The argument turns on the costs of acquiring and possessing beliefs; sometimes truth is just too costly."

Edis has given several lectures about Islamic creationism. One of his premises is that creationism in the United States is quite moderate compared to Islamic countries. Turkey for example, despite being known as a secular state, has high levels of belief in a young Earth. This is because the textbooks and curriculum in the schools do not offer both evolution and creationism, but only creationism. Teaching evolution is not part of the syllabus at all. Grothe asked Taner in 2007 if he thought that Islam could be compatible with western science. His answer was that it just depends on the type of Islam. As in Christianity there are both liberal and conservative Muslims. The more liberal their views the more compatible they are with science.

Concerning crop circles Edis wrote that we know how these are created, we know the techniques. "So we do not need to find the perpetrator of every crop circle to figure out that probably they all are human made. Many true believers remain who continue to think there is something paranormal — perhaps alien — about crop circles. But the circles we know all fall within the range of the sort of thing done in hoaxes. Nothing stands out as extraordinary."
