"Instant Karma!" is a song by English rock musician John Lennon, released as a single on Apple Records in February 1970. The lyrics focus on a concept in which the consequences of one's actions are immediate rather than borne out over a lifetime. The single was credited to "Lennon/Ono with the Plastic Ono Band", apart from in the US, where the credit was "John Ono Lennon". The song reached the top five in the British and American charts, competing with the Beatles' "Let It Be" in the US, where it became the first solo single by a member of the band to sell a million copies.

John Winston Ono Lennon was an English singer, songwriter and musician. He gained worldwide fame as the founder, co-songwriter, co-lead vocalist and rhythm guitarist of the Beatles. His work included music, writing, drawings and film. His songwriting partnership with Paul McCartney remains the most successful in history.
