Welcome to Waterloo! We are happy to welcome you as a resident, business associate, or visitor to our community.

We are a growing city, located in the heart of Monroe County, Illinois. Having recently celebrated our 125th anniversary, we have a great deal of historic charm and beauty to offer, with three museums, several restaurants and gift shops, four golf courses, quaint festivals, farmers’ market, and many more family friendly activities.

Folks have been know to stop by for a visit and decide to stay permanently!

Waterloo is a wonderful community! We have great schools, friendly neighborhoods, beautiful parks, and so much more! With our population of 10,000, we offer a small-town atmosphere that is just 20 minutes from downtown St. Louis, Missouri, a perfect combination for those who desire a slower, simpler lifestyle yet still want access to metropolitan amenities. We are the best of both worlds!

But, don’t just take our word for it – stop by and see for you yourself!

Enjoy Waterloo!
