Effingham County, Illinois

Effingham County is located in the heart of southern Illinois, at the crossroads of two major interstates. This strategic location brings a steady flow of trucks, travelers, and visitors passing through the county.

The city of Effingham is the largest community and serves as the county’s main hub. Around 34,000 people call the county home, while several older communities still reflect its strong German heritage and cultural roots.

Lake Sara is a popular destination for fishing and boating during the warmer months. Although winters can feel long, spring brings renewed activity across the county, and the annual county fair continues to attract large crowds every summer.
