The Ammanford transmitting station is a broadcasting and telecommunications facility located on Mynydd y Betws about 6 km (4 mi) to the south east of the town of Ammanford, in Carmarthenshire, Wales (grid reference SN661109).

The building was originally built by Messrs. T. Richard Jones of Ammanford for the BBC, entering service in 1968 acting as a relay transmitter for the now-defunct 405-line VHF television system.

The television broadcast primarily covered the towns of Ammanford, Brynamman, Cwmamman and indeed much of the valley of the Amman river.

[1] From this point onwards, the site has handled telecommunications services only (including service as a mobile phone mast).
