Norridge is a village in Leyden Township, Cook County, Illinois, United States.

[2] The village and its neighbor to the east, Harwood Heights, together form an enclave within the city of Chicago.

[5] 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.

In 1948, a local improvement association incorporated Norridge as a village, stymieing an effort by Chicago to annex the area.

[citation needed] The 1950s was a decade of growth and development, encouraged by the paving of sidewalks, streets, and curbs, and the installation of storm and sanitary sewers.

[7] According to the 2021 census gazetteer files, Norridge has a total area of 1.81 square miles (4.69 km2), all land.

28.37% of all households were made up of individuals, and 16.37% had someone living alone who was 65 years of age or older.
