Cadair Berwyn is a mountain summit in north Wales, UK. It is the higest point in the Berwyn range, and the higest significant summit in Wales outside the National Parks. The name cadair, meaning chair, presumably applies to the cwm on the south side of the ridge – compare Cadair Idris.
It is often reported that Moel Sych, 1 km along the ridge is of equal height, but Cadair Berwyn's spot height on the Ordnance Survey maps, where the Trig point stands, is not the true summit. Cadair Berwyn's summit, 200 m south of the trig point, is a few meters taller than Moel Sych.
