Nercwys is a rural village and community in Flintshire, Wales which is surrounded by open countryside. The community population taken at the 2011 census was 585. The older, Anglicised spelling of Nerquis can sometimes be found. It has a small school and a local bus service to Mold which is around 3 miles away. The origins of this settlement are obscure. The shape of the churchyard might indicate an early medieval origin but there is no convincing evidence to corroborate the theory. The parish church is dedicated to St Mary, dates back to the 12th century and is a grade II* listed building.
