Macoupin County

Macoupin County is an administrative division in central Illinois with Carlinville as its county seat. The area encompasses numerous small towns and rural communities that share regional governance and services.

The county was established in 1829 after being carved from parts of Greene and Madison Counties. The name comes from Macoupin Creek, which runs through the landscape.

European immigrants arrived during the coal mining era, bringing customs and ways of life that left a lasting mark on the county. You can still sense this heritage in how communities celebrate their mining past through local traditions.

The county courthouse is located in Carlinville and handles official matters for the entire region. Planning ahead and contacting the office directly is helpful for anyone needing specific services or information.
