Aladdin Sane is the sixth studio album by the English musician David Bowie, released in the United Kingdom on 19 April 1973 through RCA Records. The follow-up to his breakthrough The Rise and Fall of Ziggy Stardust and the Spiders from Mars, it was the first album he wrote and released from a position of stardom. It was co-produced by Bowie and Ken Scott and features contributions from Bowie's backing band the Spiders from Mars — Mick Ronson, Trevor Bolder and Mick Woodmansey — with the pianist Mike Garson, two saxophonists and three backing vocalists. Recorded in London and New York City between legs of the Ziggy Stardust Tour, the record was Bowie's final album with the full Spiders lineup.

Most of the tracks were written on the road in the US and are greatly influenced by America and Bowie's perceptions of the country. Due to the American influence and the fast-paced songwriting, the record features a tougher, heavier glam rock sound than its predecessor. The lyrics reflect the pros of Bowie's newfound stardom and the cons of touring and contain images of urban decay, drugs, sex, violence and death. Some of the songs are influenced by the Rolling Stones; a cover of their song "Let's Spend the Night Together" is included. Bowie described the album's title character, a pun on "A Lad Insane", as "Ziggy Stardust goes to America". The cover artwork, shot by Brian Duffy and featuring a lightning bolt across Bowie's face, is regarded as one of his most iconic images.

Accompanied by the UK top-five singles "The Jean Genie" and "Drive-In Saturday", Aladdin Sane was Bowie's most commercially successful record up to that point, topping the UK Albums Chart and garnering him immense popularity there. It also received positive reviews from music critics, although many found it inferior to its predecessor. The popularity continued throughout the latter half of the Ziggy Stardust Tour, which featured various setlist and stage production changes. In later decades, Aladdin Sane has appeared on several best-of lists and is viewed as one of his essential releases. It has been reissued several times and was remastered in 2013 for its 40th anniversary, which was included on the 2015 box set Five Years (1969–1973).
