Penhow (Welsh: Pen-hw) is a small village, historic parish and community just inside the eastern edge of the boundary of the city of Newport, South Wales, within the historic county of Monmouthshire.

The Penhow Woodlands National Nature Reserve lies a short distance to the south of the village.

It is the first known British home of the St Maur alias Seymour family which rose to national prominence in the 16th century in the person of Queen Jane Seymour, the third wife of King Henry VIII, represented today by the Duke of Somerset.

Since reopening, the shop has been managed and operated by the community and, where possible, stock has been sourced locally.
