The town is named for the Shoshone Indian tribe, most of whom live on the nearby Wind River Indian Reservation. Established as a railroad and mining town, Shoshoni lies at the intersection of U.S. Routes 20 and 26, which together were formerly known as the "Yellowstone Highway". Shoshoni has a dramatic increase in visitors in the summer, when roads to Yellowstone National Park are open. Visitors also stop to camp and fish at nearby Boysen Reservoir and the surrounding Boysen State Park. Anglers participate in fishing derbies at the reservoir, including an ice fishing derby in the winter.
Ranching is, and has been for decades, the major agricultural endeavor in the nearby area.
