Harriet McClintock Marshall (August 14, 1840–July 25, 1925) was a conductor on the Underground Railroad. She offered shelter, food, and clothing to people escaping slavery. Her house, along with other houses in Harrisburg, Pennsylvania and the Wesley Union African Methodist Episcopal Zion Church (AME Zion Church), were stops on the Underground Railroad. Her husband, a former slave, Elisha Marshall was also active in helping people reach freedom, often providing transportation. He was also a veteran of the Civil War. Marshall helped establish a monument to the Colored Troops. It resides in Lincoln Cemetery in Harrisburg, where she and her husband are interred.
