OK Computer is the third studio album by English alternative rock band Radiohead, released in 1997 on EMI subsidiaries Parlophone and Capitol Records. The members of Radiohead self-produced the album with Nigel Godrich, an arrangement they have used for their subsequent albums. Other than the song "Lucky", which was recorded in 1995, Radiohead recorded the album in Oxfordshire and Bath between 1996 and early 1997, mostly in the historic mansion St Catherine's Court. The band made a deliberate attempt to distance themselves from the guitar-oriented, lyrically introspective style of their previous album, The Bends. OK Computer's abstract lyrics, densely layered sound and eclectic range of influences laid the groundwork for Radiohead's later, more experimental work.

Despite lowered sales estimates by EMI, who deemed the record uncommercial and difficult to market, OK Computer reached number one on the UK Albums Chart and debuted at number 21 on the Billboard 200, Radiohead's highest album entry on the US charts at the time. Five songs from the album—"Paranoid Android", "Karma Police", "Lucky", "No Surprises", and "Airbag"—were released as promotional singles. The album expanded Radiohead's international popularity and has sold more than 6 million copies worldwide. In 2015, it was included by the Library of Congress in the National Recording Registry. A remastered version with additional tracks, OK Computer OKNOTOK 1997 2017, was released on 22 June 2017, commemorating the album's twentieth anniversary.
