The Heathfield transmitting station is a facility for FM and television transmission at Heathfield, East Sussex, UK (grid reference TQ566220). Opened in 1969 it uses as its antenna mast a 135 metres (443 ft) tall guyed structure, giving average transmitter height 256 metres (840 ft) above sea level. A wideband horizontally polarised aerial is required to receive both digital and analogue TV signals, although the original analogue signals are in band C/D. In July 2007 was confirmed by Ofcom that Heathfield would become a B group transmitter at DSO (Digital Switchover), though all the digital MUXES would be still be receivable on a C/D group aerial (see graph) in most areas. The station's coverage area suffers from co-channel interference problems, particularly to the south, not only with Brighton (Whitehawk Hill) but with the continent as well. It is owned and operated by Arqiva.

Along with Dover, Bluebell Hill and Brighton Whitehawk Hill, Heathfield transmits regional television services from BBC One South East and ITV1 Meridian.
