Teton County was organized in 1893. Choteau was one of the first two townships established in the county by March of that same year. The city was named in honor of the French fur-trapper and explorer Pierre Chouteau, Jr. He established one of the last trading posts on the upper Missouri River in nearby Chouteau County, which was also named in celebration of his aid in settling the region.
Choteau is host to one of the world's most important sites in paleontology, Egg Mountain. In the 1970s, renowned paleontologist Jack Horner discovered a number of fossilized dinosaur nests at this site. These fossils have yielded more information about dinosaur biology during the Cretaceous period than any other paleontological dig in the world.
