Elk Grove Village is a village located in northeastern Illinois adjacent to O'Hare International Airport and the city of Chicago. The village is located primarily in Cook County with a small portion in DuPage County. The population was 33,127 at the 2010 census. As the name suggests, Elk Grove Village is home to a small herd of elk kept in a grove at the eastern edge of the Busse Woods forest preserve for which the grove is named. Elk are not native to the area but were brought from Montana by an early resident, Busse, in the 1920s. The elk are currently maintained by the Chicago Zoological Society veterinary staff and the Busse Woods Forest Preserve wildlife biologists.
