"Knockin' on Heaven's Door" is a song by American singer-songwriter Bob Dylan, written for the soundtrack of the 1973 film "Pat Garrett and Billy the Kid". Released as a single two months after the film's premiere, it became a worldwide hit, reaching the Top 10 in several countries. The song became one of Dylan's most popular and most covered post-1960s compositions, spawning covers from Guns N' Roses, Eric Clapton, Randy Crawford and more.

Described by Dylan biographer Clinton Heylin as "an exercise in splendid simplicity", the song features two short verses, the lyrics of which comment directly on the scene in the film for which it was written: the death of a frontier lawman (Slim Pickens) who refers to his wife (Katy Jurado) as "Mama".

Robert Dylan (born Robert Allen Zimmerman; May 24, 1941) is an American singer-songwriter, author and visual artist. Often regarded as one of the greatest songwriters of all time, Dylan has been a major figure in popular culture during a career spanning 60 years.

Much of his most celebrated work dates from the 1960s, when songs such as "Blowin' in the Wind" (1963) and "The Times They Are a-Changin'" (1964) became anthems for the civil rights and anti-war movements. His lyrics during this period incorporated a range of political, social, philosophical, and literary influences, defying pop music conventions and appealing to the burgeoning counterculture.
