Jonathan D. Sarfati (born 1 October 1964) is a young Earth creationist and former New Zealand national chess champion (1987–1988).  Sarfati has a PhD in chemistry and works for Creation Ministries International (CMI), a non-profit Christian Apologetics ministry. He is the author of many articles and books about creation science.
Born in Ararat, Victoria, Sarfati moved with his family to New Zealand as a child, where he became a dual Australian and New Zealand citizen. He attended Wellington College in New Zealand, later graduating from Victoria University of Wellington with a B.Sc. (Hons.) in chemistry, and a Ph.D. in the same subject for a thesis entitled "A Spectroscopic Study of some Chalcogenide Ring and Cage Molecules". He co-authored a paper on high-temperature superconductors that was published in Nature in 1987 ("Letters to Nature"), and from 1988 to 1995, had several papers on spectroscopy of condensed matter samples published in other peer-reviewed scientific journals. In 1996, he returned to Brisbane, Australia to work for the Creation Science Foundation, then Answers in Genesis.
Sarfati was a founder of the Wellington Christian Apologetics Society in New Zealand, and has long retained an interest in Christian apologetics and the creation versus evolution debate. His first two books, Refuting Evolution in 1999, and Refuting Evolution 2 in 2002, are intended as rebuttals to the National Academy of Sciences' publication Teaching about Evolution and the Nature of Science and the PBS/Nova series "Evolution", respectively. Refuting Compromise, published in 2004, is Sarfati's rebuttal of the day-age creationist teachings of Dr. Hugh Ross, who attempts to harmonise the Genesis account of creation with mainstream science regarding the age of the earth and the possible size of the Biblical Flood, against which Sarfati defends a literal biblical timeline and a global flood. Eugenie Scott and Glenn Branch of the National Center for Science Education called Sarfati's Refuting Evolution a "crude piece of propaganda".
According to his published articles, Sarfati is a staunch critic of geocentrism, homosexual behaviour, and abortion except to save the life of the mother. While opposing embryonic stem cell research, he supports adult stem cell research.
Sarfati is a FIDE Master in chess, and achieved a draw against former world champion Boris Spassky during a tournament in Wellington in 1988, and was New Zealand's national chess champion in 1987–88.
Although tied with Rey Casse for first place in the Australian Junior Championship of 1981, he was not eligible to share the title as he was a resident of New Zealand at the time. He represented New Zealand in three Chess Olympiads: the 27th in Dubai in 1986, the 28th in Thessaloniki in 1988, and the 30th in Manila in 1992. He also represented New Zealand on top board at the 5th Asian Teams in New Delhi.
He has given blindfold chess exhibitions at chess clubs and other events, and has played twelve such games simultaneously. His previous best was winning 11/11 at the Kapiti Chess Club in New Zealand.
