The Thorn is an EP recorded by English rock band Siouxsie and the Banshees. It was released in late 1984 by Polydor and remastered in 2004 to be included on the Downside Up box set.

The purpose of the EP was three-fold: Siouxsie stated that she wanted to induct new guitarist John Valentine Carruthers into the Banshees, to try out some string arrangements, and to simply re-record tracks that had evolved on tour.^[1] Some of the strings were played by musicians of the London Symphonic Orchestra (LSO), a 27-piece orchestra called the "Chandos Players".^[2]

The Thorn features four of the band's tracks recorded with orchestral instrumentation: "Overground" originally appeared on the Banshees' debut album The Scream; "Placebo Effect" was a song from their second album Join Hands, while "Voices" and "Red Over White" were previously released as B-sides from the singles "Hong Kong Garden" and "Israel", respectively. The recording took place in Bavaria, in Germany.^[1]

The Thorn was released on 19 October 1984 by record label Polydor. The songs from the EP were later included on the fourth disc of Downside Up, a collection of the band's B-sides.
