"Diamond Hoo Ha Man" is a song by British rock band Supergrass. The single was first played live at Guilfest 2007 in Guildford, England, and this live version was then released as a free download via the band's website (as was its B-side "345"). It is the first official single from the band's sixth album, Diamond Hoo Ha, and was released on 14 January 2008 as a vinyl-only single, limited to 1,500 copies, thus limiting its chances of charting, which it failed to do. An instrumental version of the song was recorded by Biff Hyman (Mick Quinn) for the Duke Diamond and Friends: Motion Picture Soundtrack.
