Mannheim, also known as Koffman House, Kauffman House, and Coffman House, is a historic home located near Linville, Rockingham County, Virginia. It was constructed circa 1788 on a 360 acre plantation by David Coffman, a descendant of one of the first German settlers in the Shenandoah Valley. David Coffman named his masterpiece after the German city from which the Coffmans originated. Mannheim is a two-story, three-bay, stone Colonial style dwelling. It has a steep side gable roof with overhanging eaves and a central chimney. A two-story, Greek Revival style wood-frame ell with double porches was added to the rear of the dwelling about 1855. A front porch also added in the 19th century has since been removed. Also on the property are the contributing two brick slave quarters, a log smokehouse, an office, a chicken shed, and the ruins of a stone spring house. The house is representative of vernacular German architecture of the mid-to-late 18th century, as constructed in America.

Mannheim was occupied by successive generations of the Coffman family until 1880. In the mid-1990s Mannheim was purchased by a James Madison University professor who restored it to its 18th-century appearance. It was listed on the National Register of Historic Places in 2004.
