The Wreck of the Old 97 was an American rail disaster involving the Southern Railway mail train, officially known as the Fast Mail, while en route from Monroe, Virginia, to Spencer, North Carolina, on September 27, 1903. Travelling at an excessive speed in an attempt to maintain schedule, the train derailed at the Stillhouse Trestle near Danville, Virginia, where it careened off the side of the bridge, killing 11 on-board personnel and injuring seven others. The wreck inspired a famous railroad ballad, which was the focus of a copyright lawsuit and became seminal in the genre of country music.

Danville is an independent city in the Commonwealth of Virginia in the United States. The city is located in the Southside Virginia region and on the fall line of the Dan River. It was a center of tobacco production and was an area of Confederate activity during the American Civil War, due to its strategic location on the Richmond and Danville Railroad. In April 1865 it briefly served as the third and final capital of the Confederacy before its surrender later that year.
