Poquoson ( /pəkoʊsən/) is an independent city located on the Virginia Peninsula, in the Hampton Roads metropolitan area of the U.S. state of Virginia. The population was 12,150 according to the 2010 Census. The Bureau of Economic Analysis combines the city of Poquoson with surrounding York county for statistical purposes.
Poquoson, which was formerly part of York County, became an incorporated town in 1952 and an independent city in 1975. (In Virginia, municipalities incorporated as independent cities are not part of any county.) 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.
Poquoson is one of the oldest continuously named cities in Virginia. It is also one of the few to retain a name which derived from the Native Americans who inhabited the area before colonization by the English began in the 17th century.
