The 2nd West Virginia Cavalry Regiment served in the Union Army during the American Civil War. It was organized in Parkersburg, Virginia (now West Virginia) during September 1861. Most of the original members of this regiment were from southeastern Ohio, and planners thought that this regiment would become the 4th Ohio Cavalry. Their application was rejected by the governor of Ohio, so the unit became the 2nd Regiment of Loyal Virginia Volunteer Cavalry. The "Loyal Virginia" part of the name was replaced with "West Virginia" after the state of West Virginia was officially admitted to the Union in 1863. Today, the National Park Service lists them as 2nd Regiment, West Virginia Cavalry under a heading of Union West Virginia Volunteers.
