This Pronunciation Guide for Illinois Place Names is a compilation of all counties, cities, towns, townships, and villages in the state of Illinois and the pronunciation of these names as preferred by local residents. It also lists state parks and geographic landmarks such as summits, trails, ridges, and cliffs, including waterways like lakes, rivers, and creeks. A pronunciation key points users to how residents enunciate vowel sounds and consonant combinations. Click on a name to hear the pronunciation spoken aloud.
