The Radiolarian Series is an album project by experimental jazz fusion trio Medeski Martin & Wood released in three installments in 2008–2009.

In early 2008 the band announced on their official website: "Medeski Martin & Wood are planning three tours, plus three albums in 2008.

The Radiolarian Series takes its name from radiolarians (also radiolaria), amoeboid protozoa that produce intricate mineral skeletons, typically with a central capsule dividing the cell into inner and outer portions, called endoplasm and ectoplasm.

Radiolaria grow their intricately beautiful patterned skeleton around their soft core in defiance of normal biological process.

"[4] The Radiolarian Series consists of music composed and developed over the course of the band's three-part 2008 "Viva la Evolution" Tour: All tracks by Medeski Martin & Wood unless otherwise noted.
