Poquoson , informally known as Bull Island, is an independent city in the Commonwealth of Virginia. As of the 2010 census, the population was 12,150. The Bureau of Economic Analysis combines the city of Poquoson with surrounding York County for statistical purposes.
Poquoson is located on the Virginia Peninsula, in the Hampton Roads metropolitan area.
Poquoson, which was formerly part of York County, became an incorporated town in 1952 and an independent city in 1975. However, the ties remain close. Over 30 years after Poquoson became a politically independent entity, some constitutional services such as the courts, sheriff and jail continue to be shared with neighboring York County.
