The Oglethorpe Plan is an urban planning idea that was most notably used in Savannah, Georgia, one of the Thirteen Colonies, in the 18th century. The plan uses a distinctive street network with repeating squares of residential blocks, commercial blocks, and small green parks to create integrated, walkable neighborhoods.

Savannah is the oldest city in the U.S. state of Georgia and the county seat of Chatham County. Established in 1733 on the Savannah River, the city of Savannah became the British colonial capital of the Province of Georgia and later the first state capital of Georgia. A strategic port city in the American Revolution and during the American Civil War, Savannah is today an industrial center and an important Atlantic seaport. It is Georgia's fifth most populous city, with a 2020 U.S. census population of 147,780. The Savannah metropolitan area, Georgia's third-largest, had a 2020 population of 404,798.
