Gregg-Wallace Farm Tenant House is a historic home located near Mars Bluff, Florence County, South Carolina. It was built about 1890, and is representative of a typical Mars Bluff vernacular tenant house for African Americans. Tenant houses often evolved from one-room slave houses, first by the addition of a shed room at the rear and a front porch, then by the addition of a second room. It was listed on the National Register of Historic Places in 2002.
