Adelanto (Spanish for "Advance") is a city in San Bernardino County, California, United States. It is approximately northwest of Victorville in the Victor Valley area of the Mojave Desert, in the northern region of the Inland Empire. The population was 38,046 at the 2020 census.
Adelanto was founded in 1915 by E. H. Richardson, the inventor of what became the Hotpoint electric iron. He sold his patent and purchased land for $75,000. He had planned to develop one of the first planned communities in Southern California.
The name Adelanto means 'progress' or 'advance' in Spanish, and was first given to the post office that was established on the site in 1917.
Richardson subdivided his land into one-acre plots, which he hoped to sell to veterans with respiratory ailments suffered during World War I. He also hoped to build a respiratory hospital. Richardson never fully realized his dream, but his planning laid the foundation for the present day City of Adelanto.
