The Berlin Trilogy consists of three studio albums by English musician David Bowie: Low, "Heroes" (both 1977) and Lodger (1979). The trilogy originated following Bowie's move from Los Angeles, California, to Europe to rid himself of worsening drug addiction. Influences included krautrock, the German music genre, and the recent ambient releases of English musician Brian Eno. After cancelling a proposed soundtrack album for The Man Who Fell to Earth (in which he starred), Bowie embarked on the Isolar tour and then moved to Europe. Before work began on the trilogy, Bowie cowrote and produced Iggy Pop's debut solo album The Idiot, which features a sound similar to that which Bowie would explore in the trilogy. He also collaborated with Pop for his second solo album Lust for Life before recording "Heroes". Both albums were released in 1977.

Bowie recorded the trilogy in collaboration with Eno and American producer Tony Visconti. The albums featured similar recording processes. Backing tracks were recorded first, followed by overdubs, with lyrics and vocals written and recorded last. King Crimson guitarists Robert Fripp and Adrian Belew contributed lead guitar to "Heroes" and Lodger, respectively. Consequence of Sound considered the trilogy an "art rock trifecta".[1] Both Low and "Heroes" experiment with electronic and ambient music. Both contain similar structures, featuring more conventional tracks on side one and instrumental pieces on side two. On the other hand, Lodger, recorded following the Isolar II world tour, features a wide variety of musical styles, including new wave and reggae, with more accessible songs throughout; both sides are split thematically by the lyrics.

Bowie began referring to the three albums as a Berlincentred trilogy during the promotion of Lodger, although "Heroes" was the only instalment recorded completely in the city; Low was recorded mostly in France, while Lodger was recorded in Switzerland and New York City. Though considered significant in artistic terms, the trilogy has proven less successful commercially. Bowie would later call the trilogy's music his "DNA". Although the trilogy received mixed reviews on release, over time, it has garnered massive acclaim and proven highly influential. While Low provided a major influence on the postpunk genre, inspiring artists like Joy Division and Gary Numan, elements of Lodger have been identified as a precursor to world music. The American composer and pianist Philip Glass adapted the three albums into classical symphonies. They were remastered in 2017 as part of the A New Career in a New Town (1977–1982) box set.
