Roger Scott (23 October 1943 – 31 October 1989) was a British radio disc jockey. He was best known for presenting an afternoon radio show on Capital London from 1973 until 1988 and a late night Sunday show, Scott on Sunday on BBC Radio 1 until his death from stomach cancer.

Roger Scott was born in Chipping Barnet in 1943, and grew up in Surbiton. He developed an early love of the rock and roll music being created at the end of the 1950s and early 1960s. As a teenager, he began playing records out the window of his suburban London home and watching the reaction of passers-by to the music.

After a brief time as a merchant seaman, Scott found his way to the United States and joined the radio station WPTR in Albany, New York in 1966. Scott's job, based on his British accent, was to be 'friend of the Beatles', and Scott learned the craft of disc jockey, working with Boom Boom Brannigan and other legendary names at the station. Eight months later, he left WPTR to become the evening presenter at the Montreal station 1470 CFOX. From 1967 to 1971, he was known by listeners for his on-air antics and for his passionate love of music. Notable during this time was his participation in "Give Peace a Chance", recorded by John Lennon with Yoko Ono during their Bed-In for Peace at the Queen Elizabeth Hotel in Montreal.

Anticipating the launch of legal land-based commercial radio, Scott returned to the UK in 1971, only to find the introduction was not as advanced as he had anticipated. Meanwhile, he secured a position at UBN, a closed-circuit station broadcasting music to all the United Biscuits factories nationwide. It was about this time he also had a brief stint on BBC Radio 1 but, anticipating a future in commercial radio, he did so under the pseudonym 'Bob Baker'.

In 1975, he and Tim Rice were resident team captains on a short-lived BBC television pop quiz programme, 'Disco!', hosted by Terry Wogan and broadcast on Sunday afternoons. He did not enjoy working on television, and the show finished after only one series.

In 1973, Scott joined the original on-air line-up of London's Capital London. His afternoon drive-time shows became immensely popular with Londoners, generating such landmark features as the 'Three O'Clock Thrill', 'Beat the Intro' (where callers were asked to name a song before the vocals had started) and the daily 'Hitline', together with the jingle 'Grab a little piece of heaven' by David Dundas. In 1976, his regular Friday rush-hour oldies show "Cruising", first broadcast at weekends in 1973, acquired a cult following, largely owing to his introduction of obscure rock-a-billy records to his London audience for the first time. He was also one of the first people in the British media to popularise the music of Bruce Springsteen.

It was also during this time that Roger Scott helped champion the Knebworth Rock Festival in 1980. The Festival's Headliner was the Beach Boys who had just released their latest album titled "Keeping the Summer Alive". Scott was always a big supporter of the West Coast Beach Boys influence on modern popular music and in anticipation of the Rock Festival and also a series of two concerts at the Empire Pool (now the Wembley Arena), Scott had listeners vote on their all time 15 top Beach Boy Hits of all time. Two subsequent Fridays were used to play back the top songs coupled with some excellent interviews with all the then band members including some insightful interviews with band member, and producer at the time, Bruce Johnston. Additionally, Scott included one of the Wembley concerts in his Friday night live concert series.

Scott disdained the standardised playlists, market and audience research and other techniques introduced by the commercial stations in the 1980s.
