Dinas Powys (; also spelt 'Dinas Powis' in English) is a large village and a community in the Vale of Glamorgan in South Wales which takes its name from the ancient Welsh for stronghold (Dinas), and pagus (Powys), the Latin word for pagan. The literal meaning, therefore, being, "Pagan Stronghold", referring to Dinas Powys hillfort, which dates from the Iron Age. The village is south-west of the centre of Cardiff and conveniently situated on the A4055 Cardiff to Barry main road, almost merging with Penarth. It is generally regarded as a pleasant dormitory village for Cardiff's commerce and industry commuters since the city has expanded with widespread development around the Cardiff Bay area.
