"Guava Jelly" is a song recorded by the Jamaican group Bob Marley and the Wailers. It was released as a 7" vinyl single through Tuff Gong and Green Door Records. It was issued commercially with B-side track "Redder Then Red", which was misspelled on its initial printing, in 1971. It was written and produced by Marley and features uncredited lyrical contributions from Bunny Livingston. A reggae composition like the majority of Marley's works, "Guava Jelly" contains a rocksteady and island-like production with lyrics loosely based around sexual intercourse. His use of the term "guava jelly" was likely referring to a specific type of sexual lubricant. It was favorably viewed by several reviewers, with many of them finding the composition to be sexual and about love. The group placed "Guava Jelly" on several compilation albums, including Africa Unite: The Singles Collection in 2005, and Owen Gray and Herbie Mann created their own versions in 1974 and 1975, respectively.

American artists Johnny Nash and Barbra Streisand also recorded covers of "Guava Jelly" and released them as commercial singles in 1972 and 1974, respectively. Nash's version was featured on his eleventh studio album, I Can See Clearly Now (1972), and was distributed in the 7" format in Jamaica and South Africa as the record's fourth and final single. Rita Marley, Bob's wife, was upset that Nash created a cover as he would be credited for the single's success and not Marley. Streisand's rendition was included on her sixteenth studio album, ButterFly (1974), and released as the record's lead single on 16 December 1974. It divided music critics in the way that several thought her voice was not suited for reggae music. In 1991 the singer would appear on Larry King Live and admit her disappointment in ButterFly and the songs that appeared on it.
