"What a Waster" is the debut single by English rock band the Libertines.

The song received little airplay because it contains frequent profanity.

"What a Waster" was initially left off the UK edition of the band's debut album Up the Bracket but was later included as the 13th track on a subsequent re-issue.

NME included the song at number 96 in their list of 500 Greatest Songs of All Time, writing that the song "subscribed to all the classic pop single rules: under three minutes, catchy-as-hell, five chords max and instantly banned by broadcasters the world over.

"[1] All songs written by Pete Doherty and Carl Barât.
