Mynydd Llwyn-gwern or Mynydd Llwyngwern is a mountain in southern Snowdonia, Wales. It lies above the Afon Dulas to the west and the Nant Ffrydlan to the east. The summit is noted for a series of low pillow mounds.[2]

The Llwyngwern slate quarry on the west flank of the mountain operated from the 1820s until about 1950.[3] In 1972, the quarry became the site for an experiment in green living.[4] This has now developed into the Centre for Alternative Technology which occupies much of the quarry site. The centre built a wind turbine on the summit of Mynydd Llwyn-gwern.[2]

It is one of the Dyfi hills.
