Frank Turek (born November 20, 1961) is an American Wesleyan apologist, author, public speaker, and radio host.

Turek has co-authored two books (Legislating Morality and I Don't Have Enough Faith to Be an Atheist) with Christian philosopher Norman Geisler.

Turek hosts a call-in talk show called CrossExamined on American Family Radio.

Turek also hosts a television show, I Don't Have Enough Faith to Be an Atheist, which airs on the NRB Network.

Turek was raised Catholic, but he became a Protestant during his time as a Naval Flight Officer in the U.S. Navy after being recommended apologetic books written by Josh McDowell, in particular Evidence That Demands a Verdict and More Than a Carpenter.

Turek frequently delivers seminars based on I Don't Have Enough Faith to Be an Atheist at universities and churches throughout America.

[10] Geisler and Turek expand on the metaphor by claiming, "a worldview is like a box top that allows you to place the many pieces of life’s puzzle into a complete, cohesive picture.
