Yorktown is a census-designated place (CDP) in York County, Virginia, United States. It is the county seat of York County, one of the eight original shires formed in colonial Virginia in 1682. The CDP's population was 195 as of the 2010 census, while the county's population was 66,134 in the 2011 census estimate.
The town is most famous as the site of the siege and subsequent surrender of General Cornwallis to General George Washington, and the French Fleet during the American Revolutionary War on October 19, 1781. Although the war would last for another year, this British defeat at Yorktown effectively ended the war. Yorktown also figured prominently in the American Civil War (1861–1865), serving as a major port to supply both northern and southern towns, depending upon who held Yorktown at the time.
Today, Yorktown is part of an important national resource known as the Historic Triangle of Yorktown, Jamestown and Williamsburg, and is the eastern terminus of the Colonial Parkway. Yorktown is also the eastern terminus of the TransAmerica Trail, a bicycle touring route created by the Adventure Cycling Association.
One of Yorktown's historic sister cities is Zweibrücken in Germany. In the time of the American War of Independence, the Royal Deux-Ponts Regiment was commanded by Comte Christian de Forbach (son of Christian IV, Count Palatine of Zweibrücken, deputy commander was his brother Philippe Guillaume (later renamed to Wilhelm), and was one of the four regiments that arrived at Newport with Rochambeau in 1780 and went on to participate in the Battle of Yorktown on the side of the Americans in 1781. Since that time Yorktown is in very close friendship to the German city of Zweibrücken.
