Redstone Old Fort — or Redstone Fort or (for a short time when built) Fort Burd — on the Nemacolin Trail, was the name of the French and Indian War-era wooden fort built in 1759 by Virginia militia colonel James Burd to guard the ancient Indian trail's river ford on a mound overlooking the eastern shore of the Monongahela River (colloquially, just "the Mon") in what is now Fayette County, Pennsylvania near, or (more likely) on the banks of Dunlap's Creek at the confluence. The site is unlikely to be the same as an earlier fort the French document as Hangard dated to 1754 and which was confusedly, likely located on the nearby stream called Redstone Creek. Red sandstones predominate the deposited rock column of the entire region.
