James T. Staples, officially registered as the Jas. T. Staples and also known as the Big Jim, was a Tombigbee River sternwheel paddle steamer that ran a route between Mobile and Demopolis, Alabama, during the early 20th century. She was destroyed during 1913 in an explosion while docked on the Tombigbee roughly six miles (10 km) north of the current Coffeeville Lock and Dam. It was the last major maritime disaster involving a steamboat in Tombigbee River history. The disaster saw the ship enter southwestern Alabama folklore, with tales that its sinking had been foretold by supernatural occurrences.
