Evan Davies (6 January 1801 – 23 February 1888), also known by his bardic name Myfyr Morganwg was a Welsh bard, druid and antiquarian.

Born in Pencoed, Glamorganshire, it is thought that Davies received no formal education; instead he spent his early years studying Welsh Bardic Rules and teaching himself mathematics, among other subjects.

In 1842 he rose to prominence when he and John Jones of Llangollen began openly debating the subject of temperance at a meeting in Llantrisant, Glamorganshire.

Following the death of Taliesin Williams in 1847, Davies proclaimed himself archdruid, and from about 1853 he began to hold religious and druidical services near the Rocking Stone at Pontypridd.

[3] For about 25 years the practice of holding meetings at the hour of equinoxes and solstices became a Glamorgan tradition,[4] and Davies published a number of books on druidism.
