Superior was named after its founders' hometown of Superior, Wisconsin, in 1869. The post office was established in 1871 after Mineral County became the site of one of the largest gold strikes that helped settle the West.
In the 1860s and '70s, several thousand miners converged on Cedar Creek. Mining has remained central to the economy, along with the development of logging and United States Forest Service activities.
In 1908, the Superior Hotel received the first Bibles to be placed in hotel rooms by The Gideons. This is noted on a historic plaque on Mullan Road.
