Roger Roger (5 August 1911 - 12 June 1995) was a French band leader and film composer of soundtracks and library music. He also recorded under the names Eric Swan, Cecil Leuter, Freddy Alberti, Henri Giordano, Roger Roger Ensemble.

Born at Rouen, Normandy, Roger started composing for films in the 1930s, and was responsible for the famous pantomime sequences in Marcel Carné's Les Enfants du Paradis (1944). He also performed and composed music for several European radio stations, including Radio Luxembourg, Radio 37 and Europe 1.

After the Second World War, Roger became a composer of library music, i.e. music designed to evoke a particular mood in a film or television production. From the 1960s to the 1980s he often collaborated with Nino Nardini. Much of his output became available via Chappell Music, and Roger also went into partnership with Frank Chacksfield to work on several projects for the BBC.

He died in Paris in 1995. Since his death, renewed interest in light music has seen several CD albums released, both in dedicated albums and in compilations, notably of test card music, where some of Roger's music was used by the BBC in the 1970s.
