Simon Franglen (born 1963, Westminster, London, England) is an English composer of classical and film music. He is also a record producer and former musician. His credits include four of the list of top grossing films and six of the list of best-selling albums of all time.

His film work includes a number of well-known movies, including Avatar, for which he received Golden Globe and Grammy nominations for the theme song, and for being the producer of "My Heart Will Go On" from Titanic, for which he won a Record of The Year Grammy Award. Other film credits range from David Fincher's Seven, The Amazing Spider-Man, The Magnificent Seven, to arranging music for the James Bond films Skyfall and Spectre.

After showing skill with synthesizers whilst working in London recording studios as a student, Franglen was hired by Trevor Horn as a Synclavier programmer, working on Yes, Frankie Goes To Hollywood, Godley and Creme. He left Sarm West Studios to become an independent producer for acts like The Associates and a composer for commercials and TV. He composed the famous Direct Line jingle.

Franglen moved into film music when he was introduced to the composer John Barry late in the production of the score for Dances with Wolves and collaborated on the soundtrack album. He continued to work with Barry for a number of years, including on Chaplin. Other long-term collaborations were with the film composers Alan Silvestri, James Horner, and Howard Shore, for whom he created the trademark dystopian electronica for Seven by David Fincher.

He worked with producer David Foster on the soundtrack for The Bodyguard and later, produced Nicole Kidman and Ewan McGregor's "Come What May" with Foster for director Baz Luhrmann's Moulin Rouge!, where he separately acted as vocal producer for the film songs. In 1997, he worked for the first time with James Horner on the score for Titanic, for which he won a Grammy Award as producer of "My Heart Will Go On". He reconnected with Horner for Avatar, spending almost 11 months working on the score; he acted as Electronic Music Arranger and also co-wrote and co-produced the Golden Globe and Grammy nominated theme song. Horner and Franglen continued to work closely together from 2009 on films such as The Amazing Spider-Man, Franglen initially acting as arranger, then moving to score producer.
