This Article provides a novel investigation of how law both enables and constrains the ability of city residents to claim, name, and often rename their neighborhoods. A rich interdisciplinary dialogue in fields such as geography and sociology has emerged on the significance of place names, but this literature has largely ignored the legal dimensions of the phenomenon and its implications for urban governance, belonging, and community conflict. This Article's empirical exploration of the role of law in change and conflict regarding neighborhood identity thus advances the discourse both for legal scholars focused on urban dynamics and across disciplines.
