Asia are a British progressive rock band. The band was formed in 1981 as a supergroup of four members from different progressive rock bands: John Wetton (former bassist/vocalist of bands including King Crimson, Family, Roxy Music, Uriah Heep, UK and Wishbone Ash), Steve Howe (guitarist of Yes), Geoff Downes (keyboardist of Yes and The Buggles) and drummer Carl Palmer (of Emerson, Lake & Palmer, The Crazy World of Arthur Brown, and Atomic Rooster). With their debut album Asia from 1982 reaching No. 1 in several countries, Asia ranks as one of the most popular progressive rock bands in history.

The band has undergone multiple line-up changes during its history, but in 2006, the original line-up reunited. As a result, a band called Asia Featuring John Payne exists as a continuation of John Payne's career as Asia's frontman from 1991 until Wetton's return in 2006. In 2013, Howe retired from the band to continue with Yes and pursue other projects, and was replaced by guitarist Sam Coulson, completing the current lineup.
