A Virginia State Navy (or Virginia Navy) existed twice. During the American Revolutionary War, the provisional government of the Virginia Colony authorized the purchase, outfitting, and manning of armed vessels to protect the colony's waters from threats posed it by the Royal Navy.
Early in the American Civil War, after the state of Virginia seceded from the Union on April 17, 1861, it briefly had naval forces of its own; these were eventually adopted by the Confederate States Navy.
Virginia, along with the other Thirteen Colonies, was increasingly dissatisfied with the actions of Lord Dunmore, the royal governor of the colony. After the Gunpowder Incident in April 1775 and the news of the war's outbreak with the Battles of Lexington and Concord, Dunmore, fearing for his safety, fled with his family to a Royal Navy ship. There Dunmore tried to organize Loyalists in the colony to counter the rebellion.
In December 1775, the provisional assembly voted to authorize the Committee of Safety to buy, arm, and man ships to prevent the royal governor from travelling over the waterways. During the next six months, the committee purchased five ships, and ordered the construction of several more. It also commissioned its first captains: James Barron, Richard Barron, Richard Taylor, Thomas Lilly, and Edward Travis. In May 1776, the assembly established a Navy Board to oversee naval affairs, and established an admiralty court. Its ships were built across the state, but eventually this became the responsibility of the shipyard on the Chickahominy River and at Gosport. In 1779 the Navy Board was superseded by a Board of War, with merchant vessels regulated by a Board of Trade. This lasted only one year, however, and Virginia established a Commissioner of War, a Commercial Agent, and a Commissioner of the Navy to coordinate her military and trade activities.
