Sun Myung Moon (born January 6, 1920) is the Korean founder and leader of the worldwide Unification Church. He is also the founder of many other organizations and projects involved in political, cultural, artistic, mass-media, educational, public service, and other activities. One of the best-known of these is the conservative Washington Times newspaper. He is famous for holding Blessing ceremonies, better known as "mass weddings."

Moon has said, and it is believed by Unification Church members, that he is the Messiah and the Second Coming of Christ and is fulfilling Jesus' unfinished mission. He has been among the most controversial modern religious leaders, both for his religious beliefs and for his social and political activism.

Moon was born in Sangsa-ri (上思里, lit. "high-thought village"), Deogun-myon, Jeongju-gun, North P'yŏng'an Province (now in North Korea; Korea was then under Japanese rule). His father, Kyung-yoo Moon, was a scholar, while his mother, Kyung-gye Kim, was an active woman. They had six sons and seven daughters, of which Sun Myong Moon was the second son. When he was a child, Moon was heavily affected by his elder brother Yong-Su Moon's deep faith. The family went into bankruptcy when the elder brother of Sun Myung's grandfather, Rev. Yunguk Moon, gave most of the money belonging to the family to an independence movement from Japan. In 2009, the Yonhap News Agency reported that Moon had plans to establish a sacred sanctuary at his birthplace.
