Radio On is a 1979 film directed by Christopher Petit. It is a rare example of a British road movie, shot in black and white by Wim Wenders' assistant cameraman Martin Schäfer and featuring music from a number of new wave bands of the time, as well as established artists such as Kraftwerk, Devo and David Bowie. It is a journey through late 1970s Britain by way of a road trip from London to Bristol, with Robert, a DJ (played by David Beames) attempting to investigate the suicide of his brother. The radio station where Robert is a disc jockey was based on the United Biscuits Network, which broadcast to factories owned by United Biscuits.

In his 2022 book Roadrunner Nick Gilbert revisits the film, the route and its resonances 43 years later and includes contributions from Petit and others involved in the film.
