The City of Monmouth welcomes you! 

Founded in 1830 and incorporated in 1852, the Maple City is located in the western portion of Central Illinois and is the county seat for Warren County.

With a current population of 9,444, Monmouth celebrates not only its diversity of population but also its blending of agricultural, academic, industrial, business and cultural influences. In addition, our City has the good fortune to have a dynamic medical center to meet the needs of our residents.                    

We are incredibly proud of what Monmouth has to offer. We hope you find Monmouth as remarkable as we do. 

If I can ever be of assistance, please do not hesitate to contact City Hall at (309) 734-2141 or This email address is being protected from spambots. You need JavaScript enabled to view it..

Again, welcome to Monmouth!
