The Battle of Carnifex Ferry took place on September 10, 1861 in Nicholas County, Virginia (now West Virginia), as part of the Operations in Western Virginia Campaign during the American Civil War. The battle resulted in a Union strategic victory that contributed to the eventual Confederate withdrawal from western Virginia, which in turn led to the creation of the State of West Virginia two years later.
The battle took its name from a former settlement, which was named after the local Carnefix family.
