Oregon ( ) is a city in and the county seat of Ogle County, Illinois, United States. The population was 3,721 in 2010. History The land Oregon, Illinois was founded on was previously held by the Potawatomi and Winnebago Indian tribes. In fact, later, settlers discovered that the area contained a large number of Indian mounds, most in diameter. Ogle County was a New England settlement.

Phelps found a forest and river-fed valley which impressed him enough that he built his cabin there. Other pioneers followed Phelps to this site, and Phelps helped create the first church, school, grocery store, blacksmith shop, and post office in Oregon.
