Commins Coch (Welsh: Comins-coch) is a small village on the A470 in the county of Powys in Wales.

Commins Coch is notable for the narrow bridge set at right angles that crosses the Afon Twymyn.

Commins Coch is also the site of one of the 1970s holiday cottages allegedly burnt down by Meibion Glyndŵr during its campaign against English incomers.

The cottage, now restored, can be seen on the right when leaving the village travelling East.
