The Camddwr is a significant right-bank tributary of the River Towy in the eastern part of Ceredigion, mid Wales. It rises on the undulating plateau east of Garn Gron (52.2253°N 3.8247°W / 52.2253; -3.8247 (Camddwr, source)) and flows in a generally south-southeasterly direction into Llyn Brianne, a reservoir formed by the damming of the upper Towy, (52.1574°N 3.7656°W / 52.1574; -3.7656 (Camddwr, mouth)). A chapel at Soar y mynydd beside the river is often mentioned as being the most isolated in Wales.
