"Window in the Skies" is a song by rock band U2 and is one of two new songs featured on their 2006 compilation album, U218 Singles. It will be released 1 January 2007 as the second single from that album. It was recorded in September 2006 at Abbey Road Studios in London and produced by Rick Rubin.

On November 7, 2006 the Los Angeles based radio station KROQ debuted the song on US radio. This song was circulated in poor audio quality months before its release, along with four other songs (dubbed "The Beach Clips"), which were recordings by U2 fans from studio rehearsals at their house on Eze Beach, France. The words "Window in the Skies" occur only towards the end of the song
