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

The group were formed by five Charterhouse pupils, including Banks, Rutherford, Gabriel, and Anthony Phillips, and named by former Charterhouse pupil Jonathan King, who arranged for them to record several singles and their debut album From Genesis to Revelation in 1968. After splitting from King, the band began touring, signed with Charisma Records and became a progressive rock band on Trespass (1970). Following Phillips' departure, Genesis recruited Collins and Hackett and recorded Nursery Cryme (1971). Their live shows began to feature Gabriel's theatrical costumes and performances. Foxtrot (1972) was their first hit in the UK and Selling England by the Pound (1973) reached number three there, featuring their first UK hit "I Know What I Like (In Your Wardrobe)". The concept album The Lamb Lies Down on Broadway (1974) was promoted with a transatlantic tour and an elaborate stage show, before Gabriel left the group.

Collins took over as lead singer, and the group released A Trick of the Tail and Wind & Wuthering (both 1976) with continued success. Hackett left Genesis in 1977, reducing the band to Banks, Rutherford, and Collins. Their ninth studio album, ...And Then There Were Three... (1978), contained the band's first major hit "Follow You Follow Me". Their next five albums – Duke (1980), Abacab (1981), Genesis (1983), Invisible Touch (1986) and We Can't Dance (1991) – were also successful. Collins left Genesis in 1996, and Banks and Rutherford replaced him with Ray Wilson, who appeared on their final album Calling All Stations (1997). The commercial failure of the album led to a group hiatus. Banks, Rutherford and Collins reunited for the Turn It On Again Tour in 2007, and again in 2021 for The Last Domino? Tour.

With between 100 million and 150 million albums sold worldwide, Genesis are one of the world's best-selling music artists. Their discography includes 15 studio and six live albums. They have won numerous awards (including a Grammy Award for Best Concept Music Video with "Land of Confusion") and have inspired a number of tribute bands recreating Genesis shows from various stages of the band's career. In 2010, Genesis were inducted into the Rock and Roll Hall of Fame.
