• Celebrate America's Birthday in O'Fallon

    O'Fallon's biggest party of the year is July 2–4 at Ozzie Smith Sports Complex, with free concerts by Chase Bryant, Love and Theft, Sister Hazel and KONGOS, a carnival and midway, sideshows, a parade and two nights of spectacular fireworks! Check it out!

  • On Tuesday, August 2, O'Fallon voters will be asked to decide on a ballot issue that could help to shape the future of O'Fallon's parks: Proposition PARKS. If approved by the voters, this proposition will allow the City of O'Fallon to issue bonds for the construction of an expanded Alligator’s Creek Aquatic Center and the construction of a brand new passive park off of Highway DD called O’Day Park. Learn more about Prop PARKS.
