An '''urban growth boundary''' ('''UGB)''' is a regional boundary, set in an attempt to control [[urban sprawl]] by, in its simplest form, mandating that the area inside the boundary be used for urban development and the area outside be preserved in its natural state or used for agriculture. Legislating for an urban growth boundary is one way, among many others, of managing the major challenges posed by unplanned urban growth and the encroachment of cities upon agricultural and rural land.<ref>{{Cite book | year=2013 |author1=Paul James |author2=Meg Holden |author3=Mary Lewin |author4=Lyndsay Neilson |author5=Christine Oakley |author6=Art Truter |author7=David Wilmoth |name-list-style=amp | chapter= Managing Metropolises by Negotiating Mega-Urban Growth | title= Institutional and Social Innovation for Sustainable Urban Development |editor1=Harald Mieg |editor2=Klaus Töpfer | url=https://www.academia.edu/7207756 | publisher= Routledge}}</ref>

An urban growth boundary circumscribes an entire urbanized area and is used by local governments as a guide to [[zoning]] and land use decisions, and by utilities and other infrastructure providers to improve efficiency through effective long term planning (e.g. optimising sewerage catchments, school districts, etc.).

If the area affected by the boundary includes multiple jurisdictions a special [[urban planning]] agency may be created by the state or regional government to manage the boundary. In a rural context, the terms town boundary, village [[curtilage]] or village envelope may be used to apply the same constraining principles. Some jurisdictions refer to the area within an urban growth boundary as an urban growth area (UGA) or urban service area, etc. While the names are different, the concept is the same.
