Dingestow (pronounced /ˈdɪndʒstoʊ/ DINJ-stoh, Welsh: Llanddingad) is a small village in Monmouthshire, Wales.

It is located 4 miles (6.4 km) south-west of Monmouth and approximately the same distance north-east of Raglan in rural Monmouthshire.

This was under construction in 1182 by Ranulf Poer, Sheriff of Herefordshire, when it was attacked by Hywel ap Iorwerth, the Welsh lord of Caerleon, as part of his retaliation for the murder of Seisyll ap Dyfnwal at Abergavenny Castle on Christmas Day in 1175 by William de Braose.

"[3] The 17th century gentry house of Treowen, now a venue for conferences and weddings, is located just north-east of the village.

The community is served by a Village Hall[5] and a general store with a sub Post Office.
