Sad Wings of Destiny is the second studio album by English heavy metal band Judas Priest, released on 26 March 1976 by Gull Records. It is considered the album on which Judas Priest consolidated their sound and image, and songs from it such as "Victim of Changes" and "The Ripper" have since become live standards. It was the band's only album to feature drummer Alan Moore.

Noted for its riff-driven sound and the wide range of Rob Halford's vocals, the album displays a wide variety of styles, moods and textures, inspired by an array of groups such as Queen, Led Zeppelin, Deep Purple and Black Sabbath. The centrepiece "Victim of Changes" is a nearly eight-minute track featuring heavy riffing trading off with high-pitched vocals, extended guitar leads, and a slow, moody breakdown toward the end. "Tyrant" and "The Ripper" are short, dense, high-powered rockers with many parts and changes. Riffs and solos dominate "Genocide", "Island of Domination", and "Deceiver", and the band finds more laid-back moments in the crooning piano-backed "Epitaph" and the moody "Dreamer Deceiver".

Sad Wings of Destiny had a positive reception but weak sales. The band recorded their first two albums with the independent Gull label under tight budgets; after living off a single meal per day while working side jobs to support themselves, the group grew frustrated with the financial situation and signed with CBS Records for their next album, Sin After Sin (1977). Breaking their contract resulted in the rights to Sad Wings of Destiny and its demo recordings falling into Gull's hands. In retrospect, the album has received acclaim as one of the most important albums in heavy metal history, with the album's image and style going on to influence many later metal bands, as well as later Judas Priest albums.
