Chicagoland Chamber

Founded in 1904, the Chicagoland Chamber of Commerce is a private, non-profit business assistance and economic development organization. We are dedicated to helping area businesses grow as well as promoting the economic development of the region. We are 2,600 members strong, representing over 1.3 million individual employees in the six-county Northeastern Illinois region (Cook, DuPage, Kane, Lake, McHenry & Will). That makes us the largest Chamber of Commerce in Illinois and one of the largest in the nation.
