Georgetown is a town in Sussex County, Delaware state. Its population as per the 2010 census was 6,422, marking an increase of almost 40% from the previous decade. It is the county seat of Sussex County, and part of the Seaford, Delaware, Micropolitan Statistical Area.
Georgetown is unusual among Delaware municipalities in that the center of the town is built around a circle, instead of the more traditional park-like square. Straddling "The Circle" is the Town Hall; state and county buildings, including the historic Sussex County Courthouse. The circle itself is now listed on the National Register of Historic Places.
