Riziero "Riz" Ortolani (25 March 1926 – 23 January 2014) was an Italian film composer. Ortolani scored over 300 films working mostly within the Italian genres of Mondo, Giallo, and the Spaghetti Western. Ortolani also scored many Hollywood films and has had some of his compositions reused in films like Drive and Django Unchained. Ortolani's most famous composition is More, which he wrote for the infamous film Mondo Cane. It won the 1964 Grammy Award for Best Instrumental Theme and was nominated for the Academy Award for Best Original Song at the 36th Academy Awards. The song was later covered by Frank Sinatra, Kai Winding, Andy Williams, Roy Orbison, and others.

Ortolani was born on 25 March 1926 in Pesaro, Italy. He was the youngest of six children. Ortolani's father, a postal worker, gave his son a violin at age 4. Ortolani later switched to flute after injuring his elbow in a car accident. He studied at the Conservatorio Statale di Musica "Gioachino Rossini" in his hometown of Pesaro before moving to Rome in 1948 and finding work with the RAI orchestra. Though the chronology is unclear, he also likely served as a musician in the Italian Air Force orchestra, formed a Jazz ensemble, and came to the United States as a Jazz musician in Hollywood, all before scoring his first film.
