Oak Brook is a village in DuPage and Cook Counties, in Illinois. The population was 8,702 at the 2000 census. A suburb of Chicago, it is the headquarters of McDonald's and Lions Clubs International.
Oak Brook was incorporated as a Village in 1958, due in large part to the efforts of Paul Butler, a prominent civic leader and landowner whose father had first moved to the vicinity in 1898 and opened a dairy farm shortly thereafter. Prior to incorporation, the name Oak Brook was used by local residents to distinguish their community from neighboring Hinsdale and Elmhurst, going back to the founding of the Oak Brook Civic Association almost two decades earlier.
The original boundaries were smaller than the present extent of the Village, but a considerable amount of land was acquired soon after the founding of the Village, including the land that is now the site of the Oakbrook Center shopping mall, which opened in 1962.
