Kenneth Alfred Ham (born 20 October 1951) is a prominent Australian young-Earth creationist and advocate for a literal interpretation of the Book of Genesis.

Ken Ham obtained a bachelor's degree in Applied Science, with emphasis in Environmental Biology, through the Queensland Institute of Technology and, in order to begin teaching science in Australian public schools, a diploma in Education from the University of Queensland. On 30 December 1972, he married Marilyn ("Mally"), whom he describes as a "very, very submissive, supportive wife" who has "always supported me five million percent." The Ham couple have five children — four are married and one lives with them in the Cincinnati area and have seven grandchildren. In 1979, Ham co-founded what was to be later known as the Creation Science Foundation (CSF) in Queensland, Australia with John Mackay.

Ham worked for the Institute for Creation Research (ICR), a leading young-Earth organisation. In 1994, with the assistance of what is now Creation Ministries International (Australia), Ham and colleagues Mark Looy and Mike Zovath set up Creation Science Ministries, later renamed Answers in Genesis. The Christian ministry specialises in young Earth creationism and promotes the belief that the initial chapters in Genesis should be taken as literally true and historically accurate. He then began raising "tens of millions of dollars" to build the ministry.
