John Jones (1836 – 27 July 1921), better known under his nom de plume Myrddin Fardd, was a Welsh writer and antiquarian scholar born at Tan-y-Ffordd in the village of Mynytho, Llangian, Caernarfonshire.

Jones was the son of John and Ann Owen, and had an older brother named Owain, who wrote for periodicals such as Y Brython and Golud yr Oes.

[2] He remained in the blacksmith's trade for most of his life, setting up in business at Chwilog, but from 1861 onwards he was also a regular competitor at eisteddfodau, both as a poet and a prose writer.

His first book, Golygawd o Ben Carreg yr Imbill, Gerllaw Pwllheli, was published in 1858.

His 1908 book Llên Gwerin Sir Gaernarfon (Caernarfonshire Folklore) is considered his best work; it consists of folk tales from the former Caernarfonshire (now western Conwy and northern Gwynedd), collected from many sources and summarised with his own comments and explanations.
