'''Diffwys''' is a mountain in Snowdonia, Wales, near Barmouth and forms part of the Rhinogydd. On the north side is an exposure of the '''Caerdion Syncline'''. It is technically a subsidiary summit of Y Llethr, missing Marilyn status by 2m. It is therefore a sub Marilyn.
The summit has a trig point. To the north is Y Llethr and Crib-y-rhiw, to the east is Y Garn, to the south is Cadair Idris, and to the west is its top Diffwys West Top.<ref>Nuttall, John & Anne (1999).
