Eldorado, OH

Eldorado is a Preble County village in western Ohio, with 458 residents in the 2020 census and a place in the Dayton metropolitan area. The village sits in farm country between Dayton, Richmond, and the smaller communities of Preble County, where township roads matter as much as village streets. National Trail Local School District gives Eldorado a regional school connection: students join classmates from New Paris and West Manchester, along with the surrounding Jackson, Jefferson, and Monroe townships. The district formed in 1965 through consolidation, and its name fits a landscape of old routes and long rural corridors.

On Main Street, the Eldorado branch of the Preble County District Library gives the village a local library address inside a countywide system. Preble County remains largely agricultural, and its communities connect through highways, school buses, and farm traffic. The village’s scale is easy to read: a few blocks, a local branch, and roads leading outward in every direction. That compact arrangement keeps Eldorado tied to nearby towns while retaining a distinct address on the county map. Eldorado is a small Ohio village whose everyday map is made from Main Street, the library, the school district, and the fields stretching across Monroe Township.
