Mynydd Hendre-ddu or Mynydd Hendreddu is a mountain in southern Snowdonia, Wales. It is one of a line of mountains running from Mynydd Dolgoed in the north, through Mynydd Llwydiarth to Mynydd Hendre-ddu and on to Mynydd y Foel, Y Grug, Mynydd Tri-Arglwyd and Mynydd Gwyn to the south of the village of Aberangell.
