The Gorseddau Junction and Portmadoc Railway is a defunct Welsh tramway.The GJ&PR was a 2 ft (610 mm) narrow gauge railway connecting the slate quarries of Cwm Pennant with the wharves at Porthmadog harbour. It was built in 1872 partly as a conversion of the earlier 3 ft (914 mm) Gorseddau Tramway which in itself had incorporated the even earlier 3 ft (914 mm) gauge Tremadoc Tramway. It opened to mineral and goods traffic in 1875.
