Cock Sparrer is a punk rock band formed in 1972 in the East End of London, England. Although they have never enjoyed commercial success, they are considered one of the most influential streetpunk bands of all time, helping pave the way for the late-1970s punk scene and the Oi! subgenre. Their songs have been covered by many punk, Oi!, and hardcore bands.
Their style was influenced by pub rock, glam rock and raw 1960s beat music as delivered by bands like the Small Faces and The Who. Their lyrics mostly dealt with topics related to the daily lives of working class people. Their name derives from their original name, Cock Sparrow, a Cockney term of familiarity.
