Supertramp (known as Daddy from 1969–70) are an English rock band formed in London in 1969. Though their music was initially categorised as progressive rock, they later incorporated a combination of traditional rock, pop and art rock into their music. The band's work is marked by the songwriting of founders Rick Davies and Roger Hodgson and the prominent use of Wurlitzer electric piano and saxophone.

While the band's early work was mainstream progressive rock, they would enjoy greater commercial success when they incorporated more conventional and radio-friendly elements into their work in the mid-1970s, going on to sell more than 60 million albums. They reached their commercial peak with 1979's Breakfast in America, which has sold more than 20 million copies.

Though their albums were generally far more successful than their singles, Supertramp did enjoy a number of major hits throughout the 1970s and 1980s, including Hodgson's songs "Give a Little Bit", "The Logical Song", "Take the Long Way Home", "Dreamer", "Breakfast in America", "It's Raining Again", and Davies' songs, "Bloody Well Right", "Goodbye Stranger", and "Cannonball". The band attained significant popularity in the United States, Canada, Europe, South Africa and Australia. Since co-founder Hodgson's departure in 1983, Rick Davies has led the band by himself.
