Norridge is a self-governing village in Cook County that carries one of the Chicago area's most distinct geographic identities: together with neighboring Harwood Heights, it forms a complete enclave surrounded on all sides by the city of Chicago, earning its well-known nickname, the Island Within a City. That independence was no accident. In 1948, residents incorporated the village specifically to prevent annexation by Chicago, and the community has maintained its own quiet, residential character ever since. Tree-lined streets, well-kept lawns, and a connected sidewalk network give the village a settled, walkable feel despite sitting squarely within the greater metro footprint.
As a compact two-square-mile community, Norridge functions as a single cohesive place rather than a collection of distinct neighborhoods.
