Prospekt's March is the seventh EP by British rock band Coldplay, initially released on 21 November 2008 in Europe and Japan, and worldwide the following week. It features several tracks left over from the studio sessions for Coldplay's fourth studio album, Viva la Vida or Death and All His Friends. It is also available in the deluxe edition of Viva la Vida. This is their first EP since Remixes (2003).

The cover features Eugène Delacroix's original paintingBattle of Poitiers, similar to the cover art featured on Viva la Vida or Death and All His Friends (which included another Delacroix-created painting, Liberty Leading the People). On 5 November, Coldplay offered an exclusive preview of the EP via their Facebook application and through their website.

There were two singles that anchored the EP. The song "Glass of Water" entered the iTunes Top 100 songs and went on to be performed live by the band on 4Music. "Life in Technicolor II" began its existence in the charts at No. 90 in the UK Singles Chart despite not being released as an official single. It was later confirmed to be the EP's first single. It later peaked at No. 28 upon its physical release on 8 February 2009. The song was nominated at the 52nd Grammy Awards for Best Rock Performance by a Duo or Group with Vocal and Best Short Form Music Video.

Throughout the recording of Viva la Vida or Death and All His Friends, Coldplay communicated to fans through their website, and some of the song titles were revealed during the recording. The name "Poppyfields" was first revealed in September 2007; in late October 2007, a message said that "Famous Old Painters" and "Glass of Water" had been written and were being considered for the album. "Prospekt's March" appeared for the first time in December of the same year; all the notes were signed by the pseudonym Prospekt, strengthening rumours that this would be the album's title. Those songs did not make it to the album's final track listing, so were featured on the Prospekt's March EP, except for "Famous Old Painters", which was never released.
