Cwmdauddwr (rarely referred to by its correct full name of Llansanffraid Cwmteuddwr) is a village in Powys, Wales. It is contiguous with the town of Rhayader on the opposite side of the River Wye. The village is located on the B4518 road linking Rhayader with the Elan Valley Reservoirs. The parish of Cwmdauddwr corresponds approximately to the medieval commote of Cwmwd Deuddwr (Welsh for 'Commote of the Confluence'; lit. 'commote of the two waters'). It was so called because of its location where the rivers Elan and Wye join. It has also been referred to as Elenydd and Elenid. It was in the area known as Rhwng Gwy a Hafren. It was also associated with Gwrtheyrnion on the east of the Wye, together they formed a cantref. This commote should not be confused with the commote of Deuddwr in Ystlyg which is also in Powys. The village is home to a pub (The Triangle Inn), village hall and a parish church dedicated to St Bride (Welsh: Sant Ffraid). The Groe, a large park on the banks of the river, has walks, play areas and sports pitches. Rhayader railway station was situated in the village until its closure in 1963.

The Afon Elan (English: River Elan) is a tributary of the River Wye which runs through the wide expanse of upland moors, traditionally known as Elenydd, in central Wales. Its valley is the Elan Valley. The name probably arises from elain meaning 'hind' or 'fawn' in reference perhaps to the rushing, bounding nature of its course.It has its source in wet moorland on the eastern flank of Pen y Deunant in Ceredigion. It is joined by Nant Dderwen, Nant Cwta and Nant Hirin before entering the top of the Elan Valley Reservoirs at Craig Goch Reservoir which in turn discharges to Garreg-ddu Reservoir and then Caban-coch Reservoir. It emerges from this chain of reservoirs in a north-easterly direction and passes through Elan Village before turning south-east after 2 miles and making its confluence with the River Wye.
