Portmeirion is an Italianate resort village in Gwynedd, on the coast of Snowdonia in North Wales. The village is located near Penrhyndeudraeth, on the estuary of the River Dwyryd, two miles southeast of Porthmadog, and one mile from the railway station at Minffordd, which serves both the narrow gauge Ffestiniog Railway and Arriva Trains Wales (Cambrian Line).

Portmeirion has served as a location for films and television shows, notably The Prisoner.
