The Mennonite Meetinghouse (Germantown Mennonite Church) is an historic, American Mennonite church building that is located at 6119 Germantown Avenue in Philadelphia, Pennsylvania.
It was added to the National Register of Historic Places in 1973.
The first settlers in Germantown in 1683 were Dutch and Germans recruited by William Penn. Most of the settlers had a Mennonite background but joined the Quaker meeting. Sometime around 1690, several families attended non-Quaker services; the subsequently built a log church in 1708. This church was the first Mennonite Church in America. William Rittenhouse was its first minister. The log church was replaced by the present church at the same site in 1770; the replacement was built by Jacob Knorr.
