Cefn Llechid is a small area of unenclosed land in the Brecon Beacons National Park east of Sennybridge in the county of Powys, Wales.
Its plateau-like summit surface peaks at 400m where it is marked by a trig point.
A couple of small bodies of water lie in a hollow on the plateau.
The hill is owned and managed by the Brecon Beacons National Park Authority.
