Matching Mole was a short-lived UK progressive rock band from the Canterbury scene best known for the song "O Caroline". Robert Wyatt formed the band in October 1971 after he left Soft Machine and recorded his first solo album The End of an Ear. He continued his role on vocals and drums and was joined by David Sinclair, of Caravan, on organ and piano, Phil Miller on guitar and Bill MacCormick, formerly of Quiet Sun, on bass. The name is a pun on Machine Molle, the French translation of the name of Wyatt's previous group Soft Machine.
