Fort Mandan was a palisade erected at the beginning of Lewis and Clark's expedition in November 1804. It was located in the vicinity of the current town of Stanton, North Dakota.

The structure was started on November 2, 1804, in the vicinity of a village of the tribe sent on the banks of the Missouri River, about seven miles downstream from the mouth of the Knife River, in the current state of Dakota North. It was finished on the 27th. At the end of March 1805, the snow began to fall and on April 7 the expedition resumed its journey westward.
