Pipe Creek Friends Meetinghouse is an historic Friends meeting house located at Union Bridge, Carroll County, Maryland, United States. It is a 1+1⁄2 - story brick structure in Flemish bond on a stone foundation. The meetinghouse was begun in 1771 and completed the next year. A fire in October 1934 destroyed the interior, but the original benches were saved. The founders of the meetinghouse were immigrants from the north of Ireland. It was the Quaker meetinghouse attended by a great-grandfather of President Herbert Hoover.[2]
