Eryrys (Welsh pronunciation: [ɛˈrərɪs]; alternate spelling Erryrys) is a village in Denbighshire, Wales, located at approximate grid reference SJ203578, five miles south of Mold.

At 355m above sea level, Eryrys is one of a number of villages with a valid claim to be the highest in Wales; others include Bwlchgwyn, Wrexham (341m, but has a still-active church, which Eryrys does not), and Garn-yr-Erw, Torfaen (390m, but has no church or pub).

[3] A number of sources suggested that the name is derived from the Welsh Erw Yrys, or the "acre (erw) of Gyrys", sometimes linked with the "Hen Gyrys o Iâl" identified as the author of early Welsh collections of proverbs.

[citation needed] Given the similarity of the place-name to the Welsh word eryres, meaning "a flock of eagles",[4] it has also been suggested that the name refers to eagles once frequenting the high ground and prominent outcrops of the area.

Eryrys lies on the edge of the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty and many walking routes go through or around the village.
