The Commercial Club of Chicago is a nonprofit 501(c)(4) social welfare organization founded in 1877 with a mission to promote the social and economic vitality of the metropolitan area of Chicago.

The Burnham Plan is a popular name for the 1909 Plan of Chicago coauthored by Daniel Burnham and Edward H. Bennett and published in 1909. It recommended an integrated series of projects including new and widened streets, parks, new railroad and harbor facilities, and civic buildings. Though only portions of the plan were realized, the document reshaped Chicago's central area and was an important influence on the new field of city planning.
