The Lemont Area Chamber of Commerce is an organization made up of business owners, community leaders and civic groups. Members work together to promote the community and make it a better place. The Chamber's motto is "Accomplish Together What No Business Can Do Alone."

In addition to holding monthly luncheons and meetings for its members, the Chamber of Commerce also puts on several special events. Members can socialize and network at "Business After Hours" and the annual Chamber Dinner Dance. Community events such as the Quarryman Challenge and Lemont Legends Cruise Nights are also sponsored by the Chamber.
