Lancaut (Welsh: Llan Cewydd) is a deserted village and former civil parish, now in the parish of Tidenham, in the Forest of Dean district, in Gloucestershire, England, located alongside the River Wye, around two miles north of Chepstow. It occupies a narrow-necked promontory formed by a curve of the river, which acts as the border between England and Wales. Little remains of the village today, except for the roofless church of St. James.
