William Allen Fuller (April 15, 1836 – December 28, 1905) was a conductor on the Western & Atlantic Railroad during the American Civil War era.

He was most noted for his role in the 1862 Great Locomotive Chase, a daring sabotage mission and raid conducted by soldiers of the Union Army in northern Georgia.

While they were dining in the Lacey Hotel, Federal spy James J. Andrews and his party of Union volunteers commandeered the General, its tender, and a few boxcars and steamed northward.

The raiders began raising rails and cutting telegraph wires to delay their pursuers, although an attempt to burn a covered bridge failed.

With the Texas still chasing the General in reverse, the pair of trains sped through Dalton and Tunnel Hill, to the surprise of local residents and railroad workers.

At milepost 116.3 (north of Ringgold), Andrews' Raiders abandoned the General and scattered from the locomotive just a few miles short of their destination of Chattanooga.

"[1] Following his successful pursuit of Andrews' Raiders, Fuller was commissioned by Governor Joseph E. Brown on August 3, 1863, for a six-month term as a captain in the Independent State Road Guards.
