Bettws Newydd (Welsh: Betws Newydd) is a small village in Monmouthshire, in southeast Wales located about 3+1⁄2 miles (5.6 km) north of Usk, a few miles south of Clytha near Raglan, Monmouthshire.

The first part of the name of the village comes from the Middle English word bedhus, meaning "prayer house", which became betws in Welsh.

As it was largely reconstructed in the 15th century as a new oratory it was referred to as Bettws Newydd.

An old early Norman motte and bailey tump sits behind trees in the village next to the public house.

On the surrounding hills are many tumuli or prehistoric burial mounds and at Coed-y-bwnydd meaning "the wood of the gentry" in Welsh (pronounced locally as 'Coed Bonnet'), is a large Iron Age hillfort with a massive mound protecting the entrance at the east and multi-vallate earthworks and entrenchments at that side, the other side being defended by a very steep incline.
