The Reno Gang, also known as the Reno Brothers Gang and The Jackson Thieves, were a group of criminals that operated in the Midwestern United States during and just after the American Civil War. Though short-lived, the gang carried out the first three peacetime train robberies in U.S. history. Most of the stolen money was never recovered.

Train robbery is a type of robbery, in which the goal is to steal money or other valuables being carried by trains.
