The 7th West Virginia Volunteer Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War. For much of the war, it was a part of the famed "Gibraltar Brigade" in the Army of the Potomac. It was famed primarily for two major actions, a determined charge on the Sunken Road at Antietam and a late evening counterattack on East Cemetery Hill at Gettysburg that helped push back an attack by the Louisiana Tigers.
