The Lisnagarvey transmitting station is a facility for mediumwave broadcasting located in the townland of Magherageery, on the southern edge of Lisburn, Northern Ireland (grid reference J257619). It is close to Sprucefield shopping centre and about one mile from the middle of Lisburn.

The station was built by the BBC for the Regional Programme to be transmitted to Northern Ireland and it went into service in 1936. It is now owned by Arqiva.

The station includes three radio masts, including two standard lattice masts and one Blaw-Knox diamond cantilever vertical radiator. The two standard lattice masts have a wire slung T-antenna suspended between them. The Blaw-Knox radiator is the only one of its kind in Western Europe. The height of a vertical radiator is related to the frequency (or wavelength) of the service transmitted, and for maximum efficiency should be one half of the station's wavelength. Its height was originally 144.8 metres (475 ft), but it was shortened when the station's broadcast frequency was changed.

Similar masts in Europe can be found nowadays only at Lakihegy, Hungary, at Riga, Latvia, at Vakarel, Bulgaria and at Stara Zagora, Bulgaria.
