Kauffman Amish Mennonite

The Kauffman Amish Mennonites, also called Sleeping Preacher Churches or Tampico Amish Mennonite Churches, are a plain, car-driving branch of the Amish Mennonites whose tradition goes back to John D. Kauffman (1847–1913) and Noah Troyer (1831–1886) who preached while being in a state of trance and who were seen as "sleeping preachers".

In contrast to other Amish Mennonites they have retained their identity over the last hundred years and also largely the Pennsylvania German language and other Amish Mennonite traditions from the late 1800s.

In 2010, there were 16 congregations of Kauffman Amish Mennonites. In 2017 they had around 2,000 baptized members and lived mainly in Missouri and Arkansas.
