"Songbird" is a song by English rock band Oasis from their fifth studio album, Heathen Chemistry (2002), and is the first single by Oasis written by vocalist Liam Gallagher. Released on 3 February 2003, the song reached number three on the UK Singles Chart, number two on the Canadian Singles Chart, and the top 10 in Ireland and Italy. During an interview with The Matt Morgan Podcast, Liam's brother and bandmate Noel Gallagher called the track a "perfect" song.[3]

Liam has said of the song: "I like beautiful things... It's not all dark in Liam World. I take me shades off every now and again and have a look at the world and see some nice things." Noel Gallagher stated jokingly in an interview with Patrick Kielty that Liam decided to "write a song about his bird", and states the title "Song... bird" in a cave man like manner. The song was written as a tribute to then-fiancée Nicole Appleton.[4] "Songbird" was composed in the key of G major using common time at 132 beats per minute.[5]
Songbird blew my head off when I first heard it because it was that fking simple and that direct. But when Liam plays you a song he wants you to instantly fking drop dead on the spot and then, when you come around, stab yourself in the heart and be in awe of the fking sonic ability of the man.[6]
