At least five bands/artists have been called Nucleus.

1. Nucleus were a pioneering jazz-rock band from the U.K., who continued in different incarnations from 1969 to 1985. In their first year they won first prize at the Montreux Jazz Festival, released their first album (Elastic Rock), and performed both at the Newport Jazz Festival and the Village Gate jazz club.

They were led by Ian Carr, who had been in The Don Rendell & Ian Carr Quintet during the mid and late 1960s, and was a respected figure in British jazz for more than forty years. Their jazz-based music evolved from an early sound incorporating elements of progressive and psychedelic rock towards a funkier sound in the mid and late 1970s.

In August 2005 a special one-off reincarnation of Nucleus, with old and new members, performed at London's Cargo venue, to an enthusiastic reception.

Carr died on 25th February 2009, aged seventy-five..

3. Nucleus is a jam band from Humboldt County California.

Originally conceived as an acid jazz/fusion project in 2000, Nucleus has played over 500 shows around the country from bars to festivals and everything in between. Morphing into a rock trio in 2003, Nucleus continued to hit the road hard and accomplish eveything on their own drive and determination. After a few years making a name on the east coast, the band returned to Northern California to pursue its next phase of evolution. The band built a studio and began producing its own albums, kicking off with 2005's The Art of Reaching. Longtime collaborator/keyboardist Brian Swizlo joined the band during this time and the latest incarnation of Nucleus was formed. Swizlo has been an in-demand fixture of the Humboldt music scene since the 1990s as well as an L.A. session player and hip-hop producer with an instantly recognizable musical touch. With continued touring and a maturing sound, Nucleus is wowing broad audiences and gearing up for a promising 2007. With distribution from the Homegrown Music Network, CD baby, Rhapsody and itunes, Nucleus is steadily growing and widening its audience. Nucleus has released five albums to date with the sixth, Love and Gold scheduled for release in Summer 2007.
