Since 1985, the Chamber has been the voice of five counties in Illinois and Indiana and more than over 85 communities in the Chicago Southland area. The Chicago Southland Chamber of Commerce provides regional leadership, advocacy, strategic alliances and programs that unite and grow its members and the business community.​ Our goal as a regional Chamber, is to be the primary regional organization that unites businesses and communities to create an environment where:

• Business of all sizes & diversity will be attracted and thrive.
• Partnerships and alliances are created with local organizations to work together for regional development and community improvement.
• Public policy promotes strong and healthy businesses.
