Tor y Foel is a hill in the Brecon Beacons National Park in the county of Powys in Wales.

It is located on the eastern flank of Talybont Reservoir, and the summit at 551m is marked by a small cairn.

It gives excellent panoramic views over the valley of the River Usk, across to the Black Mountains and west to the Brecon Beacons.

Small diggings near the top of the hill may have been for stone suitable for use as roof tiles.

[2] The upper reaches of the hill are mapped as open country and therefore available for walkers to roam at will.
