Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States between the Atlantic Coast and the Appalachian Mountains. Its geography and climate are shaped by the Blue Ridge Mountains and the Chesapeake Bay. The state's capital is Richmond.

Its most-populous city is Virginia Beach, and Fairfax County is the state's most-populous political subdivision. Virginia's population in 2022 was over 8.68 million, with 35% living within the Greater Washington metropolitan area. Virginia's history begins with several indigenous groups, including the Powhatan.

In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the growing plantation economy, but also fueled conflicts both inside and outside the colony.

Virginia was one of the original Thirteen Colonies in the American Revolution, and several Revolutionary War battles were fought in Virginia. During the American Civil War, Virginia was split when the state government in Richmond joined the Confederacy, but many of the state's northwestern counties remained loyal to the Union, separating as the state of West Virginia in 1863.

Although the Commonwealth was under one-party rule for nearly a century following the Reconstruction era, both major political parties are competitive in modern Virginia. Virginia's state legislature is the Virginia General Assembly, which was established in July 1619, making it the oldest current law-making body in North America.

It is made up of a 40-member Senate and a 100-member House of Delegates. Unlike other states, cities and counties in Virginia function as equals, but the state government manages most local roads inside them. It is also the only state where governors are prohibited from serving consecutive terms. Virginia's economy is diverse with a strong agriculture industry in the Shenandoah Valley; high-tech and federal agencies in Northern Virginia, including the headquarters of the U.S.

Department of Defense and Central Intelligence Agency; and military facilities in Hampton Roads, the site of the region's main seaport.
