Low is the eleventh studio album by the English musician David Bowie, released on 14 January 1977 through RCA Records. The first of three collaborations with the producer Tony Visconti and the musician Brian Eno that became known as the Berlin Trilogy, the project originated following Bowie's move to France in 1976 with his friend Iggy Pop to rid themselves of their drug addictions. There, Bowie produced and co-wrote Pop's debut solo studio album, The Idiot, featuring sounds the former would explore on his next record. After completing The Idiot, sessions for Low began at Hérouville's Château d'Hérouville in September 1976 and ended in October at Hansa Studios in West Berlin, where Bowie and Pop had relocated.

An art rock record influenced by German bands such as Tangerine Dream, Neu!, Harmonia and Kraftwerk, Low features Bowie's first explorations in electronic and ambient styles. Side one consists primarily of short, direct avant-pop song-fragments, with mostly downbeat lyrics reflecting Bowie's state of mind, and side two comprises longer, mostly instrumental tracks, conveying musical observations of Berlin. Visconti created the distinctive drum sound using an Eventide H910 Harmonizer, a pitch-shifting device. The cover artwork, a profile of Bowie from the film The Man Who Fell to Earth (1976), was intended as a visual pun, meaning "low profile".

RCA refused to issue Low for three months, fearing it would be a commercial failure. Upon release, it divided critical opinion and received little promotion from RCA or Bowie, who opted to tour as Pop's keyboardist. Nevertheless, it reached number 2 in the UK and number 11 in the US. Two singles were released: "Sound and Vision", a UK top five hit, and "Be My Wife". The success prompted RCA to release The Idiot in March 1977. In mid-1977, Bowie performed on Pop's follow-up album Lust for Life before recording his next album, "Heroes", which expanded on Low's musical approach and features a similar mix of songs and instrumentals.

In later decades, critics have rated Low one of Bowie's best works, and it has appeared on several lists of the greatest albums of all time. It influenced numerous post-punk bands and its drum sound has been widely imitated. A forerunner in the development of the post-rock genre of the 1990s, Low has been reissued several times and was remastered in 2017 as part of the A New Career in a New Town (1977–1982) box set.

In 1974, David Bowie developed a cocaine addiction. It worsened over the next two years, affecting his physical and mental state. He recorded Young Americans (1975) and Station to Station (1976), and filmed The Man Who Fell to Earth (1976), while under the drug's influence. Bowie attributed his growing addiction to Los Angeles, where he moved from New York City in early 1975. His drug intake escalated to the point where, decades later, he recalled almost nothing of the recording of Station to Station.

I was in serious decline, emotionally and socially [...] I think I was very much on course to be just another rock casualty [...] I'm quite certain I wouldn't have survived the Seventies if I'd carried on doing what I was doing [...] I was lucky enough to know somewhere within me that I really was killing myself, and I had to do something drastic to pull myself out of that.

After completing Station to Station in December 1975, Bowie began work on a soundtrack for The Man Who Fell to Earth with Paul Buckmaster, who worked with Bowie on the 1969 album Space Oddity. Bowie expected to be wholly responsible for the music, but withdrew his work when he was invited to submit it along with the work of other composers: "I just said, 'Shit, you're not getting any of it.' I was so furious, I'd put so much work into it." Station to Station's co-producer Harry Maslin argued Bowie was "burned out" and could not complete the work. Bowie later sent the film's director Nicolas Roeg a copy of Low with a note that read, "This is what I wanted to do for the soundtrack. It would have been a wonderful score."

With the soundtrack abandoned, Bowie decided he was ready to free himself from the Los Angeles drug culture and move back to Europe. He began rehearsals for the Isolar tour to promote Station to Station in January 1976; the tour began on 2 February. Though it was critically acclaimed, Bowie became a controversial figure during the tour. Speaking as his persona the Thin White Duke, he made statements about Adolf Hitler and Nazi Germany that some interpreted as expressing sympathy for or promoting fascism. Bowie later blamed his erratic behaviour during this period on his addictions and precarious mental state, stating: "It was a dangerous period for me. I was at the end of my tether physically and emotionally and had serious doubts about my sanity."
