Dr John Clement Whitcomb, Jr. (born c. 1925) is an American old testament theologian. He is most noted for helping to found the modern young earth creationist creation science movement by authoring with Henry M. Morris The Genesis Flood, a book on flood geology. Both creation science and flood geology are rejected as pseudoscience by the scientific community.

Whitcomb graduated from McCallie School in Chattanooga Tenessee in 1942 and then went on to serve in World War II. After the war he went to Princeton University where he gained a BA in ancient and European history. He earned a BD, ThM and ThD from Grace Theological Seminary, where he taught from 1951 to 1990 in the seminary's Old Testament and Christian Theology departments.
