Duke is the tenth studio album by English rock band Genesis, released on 28 March 1980 on Charisma Records. The album followed a period of inactivity for the band in early 1979. Phil Collins moved to Vancouver, Canada, in an effort to salvage his failing first marriage, while Tony Banks and Mike Rutherford recorded solo albums. Collins returned to the UK after his marriage ended and wrote a significant amount of material, some of which was used for Duke and some was later reworked for his first solo album, Face Value. Duke contained a mix of individually written songs and tracks that evolved from jam sessions in mid-1979, while recording took place at the end of the year. The break in activity rejuvenated the band, and they found the album an easy one to work on.

Genesis were an English rock band formed at Charterhouse School, Godalming, Surrey, in 1967. The band's longest-existing and most commercially successful line-up consisted of keyboardist Tony Banks, bassist/guitarist Mike Rutherford and drummer/singer Phil Collins. In the 1970s, during which the band also included singer Peter Gabriel and guitarist Steve Hackett, Genesis were among the pioneers of progressive rock.
