Encyclopedic overview

Eldorado (/ˌɛldəˈreɪdoʊ, -də/) is a city in Saline County, Illinois, United States. As of the 2020 census, Eldorado had a population of 3,743. The population peaked in 1980 at 5,198. Although the city's name is spelled as if it were Spanish, the name was originally "Eldereado" or "Elder-Reado" (depending on the source)—a combination of the last names of the town's two founders, Judge Samuel Elder, his son William, grandson Francis Marion, and neighbor Joseph Read, and his brother William. According to legend, a signpainter for the railroad painted the name "Eldorado" on the train depot; as a result, the spelling and pronunciation (el-do-RAY-doh) was forever changed.

Eldorado is included in the Illinois–Indiana–Kentucky tri-state area and is a bedroom community in the Harrisburg micropolitan statistical area.
