Walterstone is a village and civil parish in Herefordshire, England, near the Welsh border and the Brecon Beacons National Park, 25 km south west of Hereford. The parish had a population of 97 in the 2001 UK Census and is grouped with Craswall, Llanveynoe and Longtown to form Longtown Group Parish Council for administrative purposes.
There is a motte-and-bailey castle in the village to the west of St Mary's church and an Iron Age hill fort on high ground 1 km to the east. The River Monnow and the Welsh Marches railway line share a valley south east of the village.
The 300-year-old village pub, the Carpenter's Arms, is situated next to the church and has been in the same family for the last 100 years.
In the 18th century, a Roman mosaic was reported to have been found in the parish. The exact site is not known but is thought to be in the Coed-y-Grafel area north of the village. Allt Yr Ynys, a 16th-century manor house 2 km south of the village, is now a country house hotel.
