Ché Ahn is a Korean-American evangelical pastor. Along with his wife, Sue Ahn, he founded Harvest Rock Church in Pasadena, California, in 1994. Originally a small, multi-ethnic congregation, Harvest Rock Church has grown into a megachurch emphasizing supernatural experiences, love, and equipping believers for revival and societal reformation. Ahn also established Harvest International Ministry in 1996, an apostolic network that connects over 25,000 churches and ministries across more than 60 countries.
As a child, Ahn immigrated to the United States with his family after the Korean War. A spiritual encounter at age seventeen redirected his path toward Christian ministry. Ahn earned a Master of Divinity and a Doctor of Ministry from Fuller Theological Seminary. He was mentored by C. Peter Wagner, who introduced him to apostolic leadership and spiritual warfare, shaping his approach to church growth and global outreach. Ahn serves as the International Chancellor of Wagner University.
