Welcome to Jersey County

Acres of woodlands, miles of sweeping hills and pastoral fields, massive limestone bluffs and, of course, two of the nation’s greatest rivers flowing along its western edges, all give Jersey County its distinctive character.

Home to Illinois’ largest state park, Pere Marquette, and the confluence of the Mississippi and Illinois rivers, Jersey County is also known for its 150 year old county fair and its scenic fall drives.

Historic communities dot the landscape of the county including Elsah, tucked into the bluffs along the Mississippi River, and Grafton sitting at the confluence of the two rivers.

Founded in 1839 and named by settlers who had relocated from New Jersey, the area has seen steady growth throughout the last two centuries while retaining its rural charm.

From apple festivals to BBQ competitions and holiday celebrations, Jersey County offers a wide range of year round activities.
