Jenna Miscavige Hill (born February 1, 1984) is an American former Scientologist. After leaving the Church of Scientology in 2005, she has become an outspoken critic of the organization. She had been a third-generation Scientologist, the granddaughter of Ron Miscavige Sr. (who also left the church in 2012), the daughter of Elizabeth and Ron Miscavige Jr. (who left in 2000) and the niece of current Scientology leader David Miscavige. Her book Beyond Belief: My Secret Life Inside Scientology and My Harrowing Escape, recounting her experience growing up and living within the Scientology movement, was published by HarperCollins in 2013. She now runs a website which she co-founded with other ex-Scientologists which provides support and discussion for people either in the church or who have left
