"O Baby" is a song written and recorded by English rock band Siouxsie and the Banshees. It was produced by John Cale and released as the first single from the band's 11th studio album, The Rapture.Melody Maker wrote : "O Baby is the wonderful prelude to Rapture" and it is "deliciously pop".

The song is much different musically and lyrically than almost all of Siouxsie and the Banshees' previous releases. It is an up-tempo love song with a skipping rhythm, light guitar work and straightforward, cheerful lyrics by Siouxsie Sioux ("...the cracks in the ground grin up at me / Even the creases in my shoes smile up at me...").

The [B-side], "B Side Ourselves", was performed by the band during all the shows of their 1995 tour.

The extra tracks were live acoustic versions of "Swimming Horses" and "All Tomorrow's Parties" (initially composed by The Velvet Underground), both recorded in December 1991 for radio station KROQ.

"O Baby" was the last Siouxsie and the Banshees single to hit the top 40, peaking at number 34 in the UK singles chart. It was also their last entry on the U.S.A. Modern Rock Tracks chart, where it reached number 21.
