Mauck's Meetinghouse, also known as Mill Creek Church, is a historic Mennonite-Baptist meeting house located at Hamburg, Page County, Virginia. It was built between 1795 and 1800, and is a 1 1/2-story, planked log structure measuring approximately 36 feet by 29 feet. The building was remodeled about 1830, with the addition of weatherboard siding (since removed) and interior balconies. The entrances feature raised six-panel Federal doors and the architrave is a simple one-section molding. It was listed on the National Register of Historic Places in 1976.
