Alzada was first established in 1878, by 9th U.S. Infantry soldiers as Camp Devin, on the Deadwood, Dakota Territory to Fort Keogh, Montana Territory telegraph line. It was called the Little Missouri River Telegraph Station, and manned by soldiers of the 7th U.S. Cavalry. Then it was named Stoneville, after the local bartender Lou Stone. It served as a stagecoach stop between Deadwood and Miles City, Montana. It was the site of a gun battle in 1884 between local authorities and rustlers known as the Exelby gang. The town's name was changed from Stoneville in 1885, because of confusion with another similarly named community. The name "Alzada" came from an early settler named Laura Alzada Shelden. Later settlers of the area were largely homesteaders. In 1890, Private Peter Thompson, a 7th Cavalry survivor and recipient of the Medal of Honor for the Battle of the Little Bighorn, moved from Lead, Dakota Territory, with his brother William and homesteaded north of Alzada on the Little Missouri River at Nine Mile Creek.
Alzada was briefly in the news in September 1997, when a B-1 bomber crashed nearby.
