"Deadwing" is the eighth studio album by Porcupine Tree, first released in 2005 after their breakthrough with "In Absentia". It was the second in a series of three albums that many consider the pinnacle of the band's artistic achievements. It also tied in with the band's new commercial success, becoming the band's best-selling album of the period.

Based on a script written by Steven Wilson and director Mike Bennion, about half of the songs were started as part of the film's score. However, when the film did not enter the production phase, Wilson instead made them the basis for the next PT album, with additional material written in collaboration with the other band members.

The album includes the classic singles: "Shallow" and "Lazarus," which Wilson still performs live with his current band. Other popular songs from the album include "Open Car" and "Arriving Somewhere But Not Here."
