Creedence Clearwater Revival, also abbreviated as CCR, was an American rock band formed in El Cerrito, California. The band initially consisted of lead vocalist, lead guitarist, and primary songwriter John Fogerty; his brother, rhythm guitarist Tom Fogerty; bassist Stu Cook; and drummer Doug Clifford. These members had played together since 1959, first as the Blue Velvets and later as the Golliwogs, before settling on Creedence Clearwater Revival in 1967. The band's most prolific and successful period between 1969 and 1971 produced fourteen consecutive top 10 singles (many of which were double A-sides) and five consecutive top 10 albums in the United States – two of which, Green River (1969) and Cosmo's Factory (1970), reached number one. The band performed at the 1969 Woodstock festival in Upstate New York, and was the first major act signed to appear there.

CCR disbanded acrimoniously in late 1972 after four years of chart-topping success. Tom Fogerty had left the previous year, and John was at odds with the remaining members over matters of business and artistic control, all of which resulted in lawsuits among the former bandmates. Fogerty's disagreements with Fantasy Records owner Saul Zaentz led to more court cases and John Fogerty refused to perform with the two other surviving members at Creedence's 1993 induction into the Rock and Roll Hall of Fame. Though the band has never officially reunited, John Fogerty continues to perform CCR songs as part of his solo act, while Cook and Clifford have performed as Creedence Clearwater Revisited since the 1990s.

CCR's music remains a staple of U.S. classic rock radio airplay; 28 million CCR records have been sold in the U.S. alone. The compilation album Chronicle: The 20 Greatest Hits, originally released in 1976, is still on the Billboard 200 album chart and reached the 600-weeks mark in August 2022. It has been awarded 10× platinum.
