Company D, 2nd Virginia Volunteer Infantry ''Berkeley Border Guards''

The 2nd Virginia, Company D or the "Berkley Border Guards" was an antebellum Virginia militia company and then a company of the 2nd Virginia Infantry, a Confederate infantry unit during the American Civil War.

This pre-war militia unit was present at the execution of John Brown, a famous abolitionist leader who, in 1859, led a raid on the United States Arsenal at Harpers Ferry, Virginia (now West Virginia). The unit's original leader was Captain John Quincy Adams Nadenbousch. They were stationed around Martinsburg, in what is now West Virginia.

During the Civil War, the company was a part of the original "Stonewall Brigade," commanded by General Thomas J. Jackson of Lexington, Virginia, originally a native of Clarksburg, Virginia (now West Virginia), and Jackson's Mill, near present-day Weston, West Virginia.
