Summit is a city in Cook County, Illinois, United States. The population was 11,161 at the 2020 census. The name Summit, in use since 1836, refers to the highest point on the Chicago Portage between the northeast-flowing Chicago River and the southwest-flowing Des Plaines River located just north of the city.

Argo is a subdivision annexed by Summit in 1911 when it was new. Named for the nearby cornstarch and baking powder manufacturing plant, it developed separately from the older part of the city. The name "Argo" is still widely used but is not part of the name of the city itself.
