David Bowie (commonly known as Space Oddity) is the second studio album by the English musician David Bowie, originally released in the United Kingdom on 14 November 1969 through Mercury affiliate Philips Records. Financed by Mercury on the strength of "Space Oddity", the album was recorded from June to October 1969 at Trident Studios in London. Gus Dudgeon produced "Space Oddity", while Tony Visconti produced the rest of the album. It featured an array of collaborators, including Herbie Flowers, Rick Wakeman, Terry Cox and the band Junior's Eyes.

Departing from the music hall style of Bowie's 1967 self-titled debut, David Bowie contains folk rock and psychedelic rock songs, with lyrical themes influenced by events happening in Bowie's life at the time, including former relationships and festivals he attended. "Space Oddity", a tale about a fictional astronaut, was released as a single in July 1969 and became Bowie's first commercial hit, reaching the UK top five.

The album was a commercial failure due to a lack of promotion, despite receiving some positive reviews from music critics. For its release in the United States, Mercury retitled the album Man of Words/Man of Music and used different artwork. RCA Records reissued the album under the title of Space Oddity following Bowie's commercial breakthrough with Ziggy Stardust in 1972, using a contemporary photo of Bowie as the artwork. The reissue charted in both the UK and the US.

David Bowie has received mixed reviews in later decades, with many finding a lack of cohesiveness. Bowie himself later stated that it lacked musical direction. Debate continues as to whether it should stand as Bowie's first "proper" album. David Bowie has been reissued numerous times, with bonus tracks and variance on the inclusion and listing of the hidden track "Don't Sit Down". Labels have used both David Bowie and Space Oddity as the title, with Space Oddity being used for a 2019 remix by Visconti.
