Gwynfryn is a hill-top village in the community of Minera in Wrexham County Borough, Wales.

[1] Like the neighbouring villages of Minera and Bwlchgwyn, Gwynfryn is associated with the development of lead mines and limestone quarries in the vicinity.

[2] The area was originally known as Plas-Gwyn ("white hall") Mountain, its name on the 1879 and 1900 Ordnance Surveys of Denbighshire, or as Pentre-Bais ("petticoat village").

According to a local story the latter name was changed to Gwynfryn by the disapproving village postmaster (or schoolmaster, in some versions).

The musician, composer and Eisteddfod adjudicator Thomas Carrington (1881–1961) was born in Gwynfryn.
