"Sweet Thing" or "Sweet Thing/Candidate/Sweet Thing (Reprise)" is a suite of songs written by David Bowie for the album Diamond Dogs. Recorded in January 1974, the piece comprises the songs "Sweet Thing" and "Candidate" and a one-verse reprise of "Sweet Thing."

In the opening line, "Sweet Thing" contains the lowest note Bowie had recorded in a studio album (C2) until "I Took a Trip on a Gemini Spacecraft" for the album Heathen (2002), where he growled the word "Well" (G1) towards the end of the song.

Bowie recorded a track with the same title, "Candidate" – but no musical similarity to the Diamond Dogs song "Candidate" and only a few words of lyrics in common – during the first several days of January 1974. It was unavailable until 1990 when it was released as a bonus track on the Rykodisc reissue of Diamond Dogs; it also appeared on the bonus disc of the 30th Anniversary Edition of Diamond Dogs in 2004.

A track now referred to as "Zion" has also appeared on bootlegs under the titles "Aladdin Vein", "Love Aladdin Vein", "A Lad in Vein", and "A Lad in Vain". Incorporating parts reminiscent of "Aladdin Sane" and what would become "Sweet Thing (Reprise)" on Diamond Dogs, this instrumental piece was generally thought to have been recorded during the Aladdin Sane sessions at Trident Studios early in 1973. However a recent estimate places it alongside recordings for Pin Ups later that year, as a preview of Bowie's next original work, leading author Nicholas Pegg to suggest that it "perhaps ought to be regarded more as a Diamond Dogs demo than an Aladdin Sane out-take". A 1973 article about Bowie recording Pinups in France accurately describes the song, which seems to confirm Pegg's theory:
