"When You Gonna Learn" is the debut single released by British funk/acid jazz band Jamiroquai. It was originally released in 1992 by Acid Jazz Records, then re-released on Sony Records in 1993 as the lead single from the band's debut studio album, Emergency on Planet Earth. The lyrical themes, like many of Jamiroquai's early songs, speak of environmental awareness.

The demo was recorded without didgeridoo player Wallis Buchanan. While the most commonly known version of the song lasts for 3:50, and can be found on the band's album, another, longer version exists. Known as the "J.K. mix", it lasts for 6:28 and appears on the vinyl version of the Emergency on Planet Earth album as well as on the "When You Gonna Learn" and "Blow Your Mind" singles.

"When You Gonna Learn" was not the first single written and issued by Jay Kay, though it is the first single as Jamiroquai. Kay's first single was actually a white label acetate called "Natural Energy", which was pressed only in three copies.Kiss 100 FM was the first radio station to play the single. The chord progressions of the song bear a striking resemblance to the chord progressions of a Johnny "Hammond" Smith's track called "Los Conquistadores Chocolatés", taken from his 1975 album Gears. The booklet of the Acid Jazz Records release of the single bears a "special thanks" note to Smith, who gave permission to Kay to use the composition's structure. It is unknown whether Hammond received any royalties. The chord progressions of the Cantè Hondo Mix of the song bear even more resemblance to "Los Conquistadores Chocolatés". The Cantè Hondo Mixes also uses the wind sound effect from Hammond's song. The cover used by Acid Jazz Records is completely different from the cover on Sony's release, although a Spanish promo issued by Sony bears the Acid Jazz Records cover. There have been legal disputes between Acid Jazz Records and Epic Records because Epic re-released the single without Acid Jazz Records' consent.
