Freeburg is a village in St. Clair County, Illinois, United States. As of 2010, Freeburg had a population of 4,354.
Freeburg lies in the fertile and rolling southern Illinois plains between the Kaskaskia and Mississippi Rivers. It was platted in 1836 as the town of Urbana by immigrants to this area from Virginia around 1800. The first European settlers of Freeburg were of English and Irish ancestry.
There were five migratory Indian tribes that crisscrossed each other in Illinois; the Peorias, Cahokias, Kaskaskias, Tamaroas, and Michiganics. It is said that Turkey Hill north of town was a popular Indian campground that also attracted many early settlers because of the view it provided of the surrounding countryside. The last Indian tribes left this area by 1820.
