Festivals and Events

Celebrate all four seasons at O’Fallon’s family-friendly festivals and events, beginning with a play by O'FallonTheatreWorks, welcoming spring at Founders' Day, patriotic pride at the Heritage & Freedom Fest (July 2-4), a dash of culture at a new Fall event in O'Day Park, and holiday magic at the Tree Lighting Ceremony and Celebration of Lights.

O’Fallon’s cultural arts and smaller events include live theater, art exhibits, heritage arts, weekly Jammin’ concerts in the park with top regional bands, and a summertime favorite, Food Truck Frenzy!
