Mexico is an unincorporated community and census-designated place (CDP) in Jefferson Township, Miami County, in the U.S. state of Indiana. The community's name probably commemorates the Mexican War of Independence. Mexico was established along an Indian trail bordering the Eel River. This trail became the Michigan Road, the first road in Miami County. Sitting along the Michigan Road was the River House Inn, owned by the parents of Indiana poet Dulciana Minerva Mason, which was at the time the only stopping point between Indianapolis and Michigan City. The post office at Mexico has been in operation since 1837.
