Libby Prison, a Confederate prison at Richmond, Virginia, where captured Union officers were held during the Civil War. The prison, a former tobacco warehouse on the James River, was notorious for overcrowded conditions, scanty and vile food, and general discomfort of inmates.

In 1889 the structure was torn down and its bricks taken to Chicago, where they were reassembled as part of a museum of the Civil War. Some of the bricks are preserved in an inside wall at the Chicago History Museum.
