Norridge is a village in Cook County, Illinois, United States. The population was 14,572 at the 2010 census. The village and its neighbor to the east, Harwood Heights, together form an enclave within the city of Chicago (i.e. they are completely surrounded by the city). Norridge is sometimes referred to as the "Island Within a City". The current President of Norridge is Daniel Tannhauser.
The name "Norridge" was suggested by resident Mrs. Link. "Nor" comes from Norwood Park Township, and "Ridge" comes from the nearby suburb of Park Ridge.
Located in Norwood Park Township, the first names of what would become Norridge were "Goat Village", due to a local resident's goat farm, and "Swamp" due to a lack of streets and the area's swamp-like conditions. Norridge began as an 80-acre (320,000 m2) subdivision that ran from Ozanam Avenue in the west to Olcott Avenue in the east and from Irving Park Road in the south to Montrose Avenue in the north. In 1948, Norridge was about to be annexed by Chicago when a local improvement association moved to incorporate as a village, ending the city's effort to incorporate it.
