Porthmadog (WHHR) railway station is the southern terminus of the Welsh Highland Heritage Railway and serves the western end of the town of Porthmadog in Gwynedd, Wales.

The station opened on 2 August 1980 and was originally a simple wooden shed situated in the car park.

In January 1986 a portable building was installed at the end of the platforms for use as a waiting room and café.

Initially it replaced the wooden shed and was subsequently extended to the east in 1993 to double the size of the shop.

This siding is now used to store various historic wagons, considerably enhancing the period feel of the station.
