A party of 22 men came to the Antimony area in 1873 on a mission to make peace with the local Fish Lake band of Indians. They caught several coyote pups here, and named the place Coyote. The first permanent settlement was established, with the name of Coyote, in 1878. In 1880, deposits of the antimony ore stibnite were found in Coyote Canyon, and a mining industry began. This resulted in the town's renaming, in 1921, to Antimony.
Antimony is known throughout Central Utah for its 4th of July fireworks display. Under the direction of visionary Mayor Shannon Allen, the town moved its annual fireworks display from the town park to the bluffs overlooking Otter Creek Reservoir. This allowed the town to take advantage of a unique water venue for the fireworks. The fireworks are shot over the lake, reflecting off the water. The fireworks have become so popular that hundreds of residents of nearby towns forego their own towns' fireworks displays to see Antimony's display.
Funded by donations, Antimony almost certainly spends more, per capita, on fireworks than any other town in the state of Utah.
