Bressay transmitting station is a broadcasting transmission facility for the Shetland Islands, located on the isle of Bressay, owned and operated by Arqiva (previously National Grid Wireless). The transmitting station is based on the Ward of Bressay, the island's highest peak.

The facility includes two steel lattice towers both over 70m high. It first came into service on 1 April 1964 transmitting BBC Television on Band I VHF channel 3 and the Scottish Home Service, Light Programme and Third on Band II VHF, using the same frequencies as today. (Home Service now Radio Shetland, Light R2 and Third R3).^[1]
