As Mayor of Warrenton let me welcome you to the Warrenton Website. We are glad you stopped by. Located on Interstate 70 in east central Missouri we feel we offer the best of both worlds. One hours drive time will find you anywhere in the St. Louis metropolitan area or on the campus of the largest state university in Columbia. Any of our 7,000 residents can tell you of our small town feeling yet the convenience to all the big city amenities that makes this a great place to live. Use our links to see what our city government can offer you or to obtain necessary forms to help you do business with us. We have included pathways to local education, commerce, recreations, and an upcoming events calendar. After your cyber visit we hope you come and visit us in person whether for our outlet shopping, sight seeing, or just to say “hello”. Enjoy your visit and we hope to see you again soon.

Thank you,
Mayor Greg Costello
