Penrhyndeudraeth (headland/promontory with two beaches in Welsh) is a village in Gwynedd, Wales. It is located between the Traeth Mawr (big beach), the now largely reclaimed estuary of the River Glaslyn, and the Traeth Bach (little beach), the estuary of the River Dwyryd. The village is close to the mouth of the River Dwyryd on the A487 from Porthmadog.
The village has two stations, Penrhyndeudraeth railway station on the southern side of the village on the Cambrian Coast Railway from Pwllheli to Shrewsbury and to the north, Penrhyn railway station, on the A4085 near the top of the hill, on the Ffestiniog Railway.
The village is at the junction of the A487 with the A4085 which connects with Beddgelert and Caernarfon. The first section of this road is very narrow and rises steeply through Upper Penrhyn. In places it is so narrow that only a single vehicle can pass.
