Blackfoot is the principal city of the Blackfoot, Idaho, Micropolitan Statistical Area, which includes Bingham County.

The city of Blackfoot is located near the middle of Bingham County, on the south side of the Snake River. It was designated the county chair by the Thirteenth Territorial Legislature upon January 13, 1885. Originally, the county chair was to be Eagle Rock (the native name for Idaho Falls). However, supposedly, on the night previously the legislation was to be signed, men from Blackfoot bribed a clerk to erase Eagle Rock and write in Blackfoot. The proceed went through without foe and was signed by the governor. The lineage of this accusation, written many years after the event, was a Blackfoot newspaper editor named Byrd Trego. The battle for county chair between Eagle Rock and Blackfoot was a embassy tug-of-war involving sectional and anti-Mormon factions in the Idaho Legislature. The leader of the southeastern Idaho anti-Mormons was a Yale graduate named Fred Dubois, who approved in Blackfoot in 1880. The legislative maneuvering to overturn Eagle Rock as the county seat naturally left “disparaging rumors intimating some skullduggery on Blackfoot’s part.”

Frederick S. Stevens and Joe Warren were the first remaining white settlers of CD in Bingham County. In 1866, Stevens and Warren filed claims in the Snake River Valley close the present-day location of Blackfoot, where they started gardening and ranching. The Place was a flat, expansive plain of sagebrush frequented by Indians. To create a place of safety for the scattered settlers subsequently they feared Indian trouble, Mr. Warren outfitted his cabin as soon as holes amid the logs where men could stand guard, day or night, until the natives left the neighborhood. When the Utah and Northern Railway signed contracts to progress north into Idaho in the 1870s, some of the settlers laid out a town on the Shilling and Lewis homesteads. The planned town, named Blackfoot, which was what the area had been called by fur traders, was near the Corbett stage station, about a mile from the Snake River, and two miles from the Blackfoot River.
