Jealous Guy is a song by English rock musician John Lennon from his 1971 album Imagine.

Lennon began writing the song in 1968, when, as “Child of Nature”, it was among the many songs demoed by the Beatles before they recorded their self-titled double album (also known as the “White Album”). The lyrics were originally inspired by a lecture given by Maharishi Mahesh Yogi in early 1968, when the Beatles attended his spiritual retreat in Rishikesh, India. In its rewritten form, the song serves as a confessional in which Lennon addresses the feelings of inadequacy that resulted in his failings as a lover and husband.

“Jealous Guy” has been recorded by many musicians including Aslan, Roberto Bellarosa, Donny Hathaway, Frankie Miller, Roxy Music, Deftones, and indie-band Spector. Lou Reed covered the song for a 2001 Lennon tribute concert.

It was also sampled by Chance on the song “Juice,” but was not cleared for streaming platforms.
