Hillsboro is a city in and the county seat of Montgomery County, Illinois, United States. The population was 5902 at the 2020 census.
The community was founded in 1823 and incorporated on March 26, 1913. There is some doubt about the origin of the city’s name. The local terrain is quite hilly, as a result of the drainage of the Shoal Creek watershed, causing widespread belief that this is the name’s source. Alternatively, there is the belief that it was named for Hillsborough, North Carolina, the home of some of the early settlers, including Hiram Rountree and John Nussman.
