The Andy Gibson was a steamboat that serviced the headwaters of the Mississippi River in the U.S. state of Minnesota from 1884 to 1894.
After her retirement, the ship was left in a drydock outside her home port of Aitkin, Minnesota, and gradually dismantled for parts.
It is thus unique among U.S. shipwrecks for still resting on a drydock cradle.
The Andy Gibson shipwreck (Smithsonian trinomial 21AK109) was listed on the National Register of Historic Places in 2012 for having state-level significance in the themes of commerce, engineering, entertainment/recreation, maritime history, non-aboriginal historic archaeology, and transportation.
It was nominated for comprising the rare and well-preserved remains of a Mississippi River steamboat.
