Meliden (Welsh: Gallt Melyd) is a village between Prestatyn and Dyserth in Denbighshire, Wales. It grew up around the locality of lead mines and limestone quarries.
The placename "Meliden" has variously been claimed to be derived from that of Bishop Melitus or St. Melyd (the village has the church of St. Melyd as its main place of worship); its Welsh placename, "Gallt Melyd", means "wooded hill of Melyd".
The railway between Prestatyn and Dyserth, long since lifted and formerly with sidings in the village, is now a public walkway and nature trek.
It has a 9-hole golf course, which is split in half by the former railway/nature walk.
