The Llandyfriog transmitting station is a broadcasting and telecommunications facility located on high ground several kilometres east of the town of Newcastle Emlyn, Ceredigion, South Wales. It was built in 1980 to relay VHF radio and UHF television to Newcastle Emlyn and the area in general. The site has a 25 m self-standing lattice mast erected on land that is itself about 105 m above sea level and acts as an off-air television relay of Preseli, about 20 km to the west.

Since Winter 1981[1] Llandyfriog has transmitted FM radio, acting as an off-air relay of Blaenplwyf about 50 km to the north. In Spring 1983[2] the radio services were upgraded to stereo.

Currently, Llandyfriog transmitter provides DVB-T digital television to the area, along with FM radio.
