Welcome to Thomson, IL, a village in northwest Illinois located on Route 84.  This section of IL 84 along the Mississippi River is also known as “The Great River Road”, ...

one of America’s most scenic routes. Over the years, Thomson has been known for its export of melons and other produce, exceptional hunting, fishing, recreational sports, and the unused Thomson Correctional Center.

Thomson is a great place to live, work and play. Our seemingly quiet little community is bustling with activity. With an eye on the future while holding to our agricultural roots, Carroll County sees progress through thriving business, excellent schools and an outstanding quality of life for all.

The views of the river and marsh are beautiful, and the birding is great, pelicans, sandhill cranes, orioles, and many others, both water birds and songbirds.
