Hyun Jin Moon (Born April 10, 1969), is the third son of Unification Church founder Sun Myung Moon and Hak Ja Han. He is married to Jun Sook Kwak (Born December 24, 1967), daughter of Unification Church leader Chung Hwan Kwak, through an arranged marriage on March 31, 1987. They have eight children.

After Sun Myung Moon and Hak Ja Han Moon's oldest son Hyo Jin Moon manifested long-term problems with substance abuse, infidelity, and violence, and after Heung Jin Moon (the second oldest son) died in 1984, Hyun Jin Moon - the next oldest living son - became widely expected to become Rev. Moon's next-generation successor. He has already assumed a number of top leadership positions.

He is a graduate of Columbia University, and holds Masters degrees from Harvard Business School (1998) and the Unification Theological Seminary. Church publications refer to him as "Dr. Hyun Jin Moon"; this honorary title was bestowed on him by Sun Moon University in Korea.
