Tremadog (formerly Tremadoc) is a village in the community of Porthmadog, in Gwynedd, north west Wales; about one mile (1.6 km) north of Porthmadog town centre. It was a planned settlement, founded by William Madocks, who bought the land in 1798. The centre of Tremadog was complete by 1811 and remains substantially unaltered. Tremadog hosted an unofficial National Eisteddfod event in 1872.
