Nick Rhodes (born Nicholas James Bates; 8 June 1962) is an English keyboardist and producer, best known as a founding member and the keyboardist of Duran Duran. He has also been the only constant member of the group since their inception in 1978.

Rhodes has been involved in several side projects outside of, but related to, Duran Duran: he released an album with Arcadia in 1985 (featuring Duran Duran members Le Bon and Roger Taylor), and recorded and performed as the Devils in 2002 with Stephen Duffy, longtime musical friend and the original lead singer of Duran Duran. In March 2013, he released the TV Mania side project with former Duran Duran guitarist, Warren Cuccurullo.

Nicholas James Bates is the only child of affluent parents who were the owners of a Birmingham toy shop. He attended Woodrush High School in Wythall, north Worcestershire. Bates left school in 1978 at the age of sixteen, and founded Duran Duran with his childhood friend John Taylor (who then played lead guitar) and Taylor's art school friend Stephen Duffy (vocals, bass, guitar). Having considered band names such as 'RAF', 'Arabia', 'Industry' and 'Arcadia', they named their band after "Dr. Durand Durand", Milo O'Shea's character from the sci-fi film Barbarella the day after the movie had been broadcast by BBC 1 on 20 October 1978. The three of them made their first recordings on a cassette tape recorder above Bates' parents' toy shop and played their first gig on 5 April 1979 at Birmingham Polytechnic, and were joined by Simon Colley (clarinet and bass) soon after. In June 1979 Duran Duran opened for the band Fashion at the Barbarella's club in Birmingham, but following the departure of Duffy and Colley reformed soon after with vocalist Andy Wickett and drummer Roger Taylor. At this point Bates' stage name was Dior Bates. After several personnel changes Duran Duran finally settled on the line-up including guitarist Andy Taylor and lead singer Simon Le Bon in May 1980 and were eventually signed to EMI.

Born Nicholas Bates, he decided to change his name for aesthetic reasons. The decision was finally made during Duran Duran's first official interview when the journalist asked his name and he made a snap decision based upon options he had been considering, he answered Nick Rhodes and never questioned it again. As the band coalesced into its final line-up in 1979–1980, Duran Duran started playing at a local Birmingham club called the Rum Runner. The club owners became the band's managers, and Rhodes began working at the club as a disc jockey.

Rhodes reportedly owns the Duran Duran name; this was mentioned in the Andy Warhol diaries. In the entry for October 5, 1986, Warhol told his diarist Pat Hackett: "One of the Taylors isn't in the group anymore but Nick owns the name so it's still Duran Duran." In 1986, Andy and Roger Taylor left the band, returning in 2001 to reunite and create the Astronaut album.

Emerging as one of the most successful bands of the New Romantic scene in the early 1980s, Duran Duran, of which Rhodes was a co–founding member, were innovators of the music video and a leading band in the MTV-driven Second British Invasion of the US. By 1984, the band had achieved levels of fame similar to Beatlemania. The band's first major hit was "Girls on Film" (1981), from their self-titled debut album, the popularity of which was enhanced by a controversial music video. The band's breakthrough second album was Rio (1982), a worldwide hit.

The band achieved rapid success, and Rhodes was a driving force throughout. An unschooled musician, he experimented with the sounds his analogue synthesisers were capable of, but shied away from the "novelty" sounds of some other early synth bands. The distinctive warble of "Save a Prayer", the keyboard stabs of "A View to a Kill", and the string sounds of "Come Undone" and "Ordinary World" are some of his most recognisable creations, as well as the futuristic oscillating synth that characterised Duran Duran's self-titled first album. He popularised the Crumar performer on the early records.

Rhodes was also quick to recognise the potential of the music video, and pushed the band to put more effort into their early videos than seemed warranted at the time (before the advent of MTV). Barely twenty when the band hit major stardom, he cultivated an androgynous and sometimes flamboyant image, wore heavy makeup, and changed his hair colour at whim. By the late 1990s, Rhodes had begun writing lyrics for Duran Duran, as well as music. His digitally altered voice is heard on the title track to the 1997 album Medazzaland.
