Septober Energy is the only album of the jazz/progressive rock big band Centipede. Produced by Robert Fripp, it was originally released 1971 in the UK as a double LP, and 1974 in the USA with a different cover. A remastered CD release, using the USA cover, was released in 2000.

The album is a four part suite consisting of four tracks of about 20 minutes each.

Septober Energy - Part 4 is based on the instrumental track Green and Orange Night Park that was part of The Keith Tippett Group's 1970 album Dedicated To You, But You Weren't Listening. Another version, titled Septober Energy and including vocals, can be found on the album The Bristol Concert by Mujician and The Georgian Ensemble, recorded 1991.
