Clun Forest is a remote, rural area of open pastures, moorland and mixed deciduous/coniferous woodland in the southwest part of the English county of Shropshire and also just over the border into Powys, Wales. The ancient Offa's Dyke runs north–south through the area (and can be walked by the Offa's Dyke Path). It gives its name to a deanery of the Church of England's Diocese of Hereford.
