Morfa Mawddach railway station is an unstaffed station located on the outskirts of the village of Arthog in Gwynedd, Wales, on the Cambrian Coast line between Machynlleth and Pwllheli. Built by the Aberystwith and Welsh Coast Railway in 1865, it was formerly the junction station for the Ruabon to Barmouth Line. Since the closure of the Ruabon to Barmouth line in 1965, it remains open, as a minor station on the Cambrian Line.
