The Hellissandur longwave radio mast is a 412 m tall guyed radio mast formerly used for longwave radio transmissions of RÚV. It is situated at Gufuskálar, near Hellissandur on the Snæfellsnes peninsula of West Iceland. It is currently the tallest longwave radio mast in the world and the tallest above ground structure in Western Europe.
It formed part of RÚV's longwave service. It was intended to fill in gaps of the FM radio, serve seafarers and as a critical communications facility. It previously operated in parallel with the less powerful Eiðar longwave transmitter to form nationwide longwave coverage, but Eiðar was demolished in 2023.
