Discography: The Complete Singles Collection is the first greatest hits album by English synth-pop duo Pet Shop Boys. It was released on 4 November 1991 by Parlophone.
 
Discography is a collection of all of the singles by Pet Shop Boys up to 1991. It is an 18-track compilation, 16 of which are singles released to that date, while the last two ("DJ Culture" and "Was It Worth It?" are new songs recorded exclusively for this album. The album contains the duo's cover version of U2's song "Where the Streets Have No Name", which later in the song breaks into the chorus of Frankie Valli's "Can't Take My Eyes Off You". Although the album's songs were released in some other form, this compilation only features seven-inch versions.
 
Around the time of the release of Discography, Pet Shop Boys also released the video compilation Videography, consisting of the music videos for each of the songs on this album in a slightly different order and with the song "Was It Worth It?" being replaced with "How Can You Expect to Be Taken Seriously?", which itself was not on the audio versions of the album, despite being part of a double A-side with "Where the Streets Have No Name (I Can't Take My Eyes off You)" (the exclusion being due to the constrictions of the CD's running time).
