Peter Hoover (born 18 May 1960) is an author familiar to many conservative Christians of Anabaptist and similar heritage in the United States, Canada and western Europe. He is a member of the non-sectarian Rocky Cape Christian Community in Tasmania, Australia.
Peter Hoover is the son of prominent Mennonite minister Anson Hoover (1920-2008) and his wife Leah (Martin) Hoover (1895-1974) He was born in Kitchener, Ontario as the sixth and last child of his parents. He is married to Susan (Krahn) Hoover and had nine children with her. He has worked in Canada, Mexico, Costa Rica, United States, Chile, and Australia. He previously was a sermon leader in the Elmendorf Christian Community, an independent Schmiedeleut colony of the Hutterites in Mountain Lake, Minnesota.
In 2006, Hoover was featured on the American television program, Dr. Phil, for his involvement in an effort to find and recover the children of an American mother whose father was concealing them in a Christian community in Belize.
In 2010, Hoover was subject to a brain tumor. It was surgically removed in the Royal Hobart Hospital on 14 July, taking away much of his ability to read and write. In his email newsletters, which were often rambling due his disease, he spoke of what he believed was his imminent death. This proved not to be case as he has since regained most of his former abilities.
Hoover's books have focused on the stories of Christians in recent centuries who have most closely reflected the relationships, values, zeal and impact which Christians originally claimed in the New Testament and ante-Nicene period. His books include Secret of the Strength (What Would the Anabaptists Tell This Generation?), which is published in both English  a German edition in Europe (as Feuertaufe. Das radikale Leben der Täufer. Eine Provokation) , and an online Spanish edition. Also, he has written Behold the Lamb (The Story of the Moravian Church), and The Russians' Secret (What Christians Today Would Survive Persecution?), and The Mystery of the Mark: Anabaptist Missions under the Fire of God .
In Radical Anabaptists Today (online in five parts) he tells the story of the Wanner family, a family in search of the true church in the environment in which the Noah Hoover Mennonites, the Orthodox Mennonites, the "Christian Communities" of Elmo Stoll emerged.
