''Once On This Island'' is a musical adaptation of Rosa Guy's book ''My Love, My Love, or The Peasant Girl''. With music by Stephen Flaherty and a book by Lynn Ahrens, the musical debuted on Broadway in 1990, and its first Broadway revival opened in December 2017. The show has been relatively successful, with three official cast recordings.

The story is a loose Caribbean retelling of "Literature/TheLittleMermaid" tale, though this only becomes more obvious towards the end. On an island in the French Antilles, there is a strong gap between the rich and poor. The peasants, alienated because of their darker skin, labor and pray to the Gods every day, while the Grand Hommes ([[BilingualBonus great men]]) live a carefree life. The four gods (Asaka, mother of the Earth, Agwe, God of water, Erzulie, [[LoveGoddess Goddess of love]], and Papa Ge, [[TheGrimReaper demon of death]]) are temperamental and constantly cruel. However, during one of Agwe's greatest floods, he decides to spare a young orphan girl. She is found and taken in by two peasants - Mama Euralie and Tonton Julian.

Désirée Dieu Donne (known to everyone as Ti Moune) dreams of more than just peasant life, though. Her prayers to the gods are answered when Daniel Beauxhomme, son of one of the wealthiest men on the island, crashes his car in her village (courtesy of Agwe) and she must take care of him. Determined to pursue her sudden love for the boy, she leaves for the world of the rich. But not only did she make a [[DealWithTheDevil deal with Papa Ge]] to let Daniel live, she is not welcome in this bright new world.

Most people might be more familiar with the Junior version - Once On This Island Jr. got its own book, with shortened songs and [[{{Bowdlerise}} some of the more mature themes edited out]]. This version is still regularly performed by schools and youth theatre groups throughout the US and the UK.

!!Tropes in this show:

* BittersweetEnding: [[spoiler: Ti Moune dies and everyone is devastated, but she is reincarnated as a tree that literally breaks down the walls of the Beauxhomme grounds. Daniel's son will find his eventual true love -- a peasant girl -- in it, and ''they'' will live Happily Ever After.]] This was changed from the complete DownerEnding of the book.
* {{Bowdlerise}}: In order to make the junior version more accessible to middle and high school students, the racial divide between the ButNotTooBlack rich and the very dark-skinned poor is completely removed. The song relating to the history of Daniel's family is removed from the junior version because of this tension (the progenitor of his family was the result of [[SonOfAWhore an affair between a French planter and a peasant woman]]). However, the "Some Girls" song is also cut, resulting to Daniel having ''virtually no singing'' at all.
** Some Junior productions [[spoiler: omit Ti Moune's forced suicide and have the gods simply turn her into a tree]], although some do keep it.
* ButNotTooBlack: Daniel and the rest of the Grand Homme.
* CrowdSong: "We Dance", "Pray" and its reprise, "Why We Tell The Story".
* CutSong: "Come Down From the Tree", a solo for Mama Euralie, was cut by the time the show premiered in New York, as was "When Daniel Marries".
* DarkReprise: "Pray" is in itself something of a dark reprise (it's based in the melody of "We Dance" played in a minor key), and "Forever Yours" and "The Human Heart" both get dark reprises at the end.
** Arguably, the "Pray" reprise is slightly darker too.
* DealWithTheDevil: Ti Moune's deal with Papa Ge.
* DisposableFiance: Inverted with Andrea.
* EveryoneHatesHades: Papa Ge is portrayed here as a pretty unpleasant guy, to say the least.
* GenderFlip: In the 2017 Broadway revival, Papa Ge is portrayed by actress Merle Dandridge (she's still credited as ''Papa'' Ge, however).
* TheGrimReaper: Papa Ge.
* TheIngenue: Ti Moune.
* IWantSong: "Waiting For Life", and technically "Some Girls" as well.
* JerkassGods: Erzulie messes around with innocent mortals' emotions in order to show up Papa Ge, who is just as eager to prove his superiority by forcing a girl to kill her lover. Agwe has a tendency to cause storms that kill people and ruin livelihoods just because he's in a bad mood. Asaka doesn't ''do'' much in the way of jerkassery, but seems perfectly content to take part in the others' petty disputes.
** JerkWithAHeartOfGold: Despite it all, [[spoiler: Asaka hears and protects Julian on his journey as well as taking Ti Moune under her wing in "Mama Will Provide", Agwe recognizes and spares Ti Moune due to her prayers in "Rain", Erzulie blesses Ti Moune and Daniel's love in "Human Heart" and is the first to speak up on Ti Moune's behalf during the Gods' quarrel after "Waiting For Life", and all of the Gods, even [[EveryoneHasStandards Papa Ge]], are touched and weep for Ti Moune after her sacrifice for Daniel, and work together to spare her that fate]]
* LoveAtFirstSight: Justified, as Erzulie is pulling the strings.
* LoveGoddess: Erzulie is an interesting take on this trope, as she seems genuinely hoping for Ti Moune to succeed in winning Daniel's heart, but it's more to prove a point to Papa Ge-quinessentially, she and Papa Ge are in something of a pissing contest to prove if love or death is the stronger force, and she'll resort to messing with emotions to do so.
* MakingASplash: Agwe the water god frequently floods the island.
* PetTheDog: Depending on how Andrea's actress plays it. Despite trying to lure Ti Moune to humiliate herself, when Ti Moune ends up dazzling everyone, Andrea compliments Ti Moune's dancing and thanks her for healing Daniel. Andrea seems to feel awful that Ti Moune was not informed of Daniel's engagement and tries to break the news to her in the kindest way.
* PoorCommunicationsKills: What breaks Ti Moune's heart. Daniel sincerely does love her, but it's implied he intended to have her as a mistress rather than a wife as he feels he cannot defy his match to Andrea.
* PrinceCharming: Daniel is this in Ti Moune's eyes.
* RichBitch: Andrea. She spends most of the ball sequence trying to humiliate poor Ti Moune.
* ShoutOut: To ''The Little Mermaid'', when Asaka says "A fish has got to learn to swim on land!"
** There's more. In one scene, Ti Moune has to wear painful shoes (referencing the Little Mermaid constantly feeling as if she is to be stabbed by daggers). Ti Moune is also asked to dance for Daniel and Andrea, referencing the mermaid serving as the prince's dancing slave.
** There is the penultimate scene, which brings the fairy tale full-circle, where [[spoiler: after Daniel betrayed her to marry Andrea, Ti Moune must kill Daniel with a dagger to escape her deal with Papa Ge, and she, of course, refuses, compelling her to drown herself.]]
** In the musical, [[spoiler: Ti Moune being reborn as a tree is meant to be the counterpart to becoming a "daughter of the air."]]
* StarbucksSkinScale: In the song telling of Daniel's family history, Beauxhomme's skin is described as being similar to "coffee mixed with cream."
* StarcrossedLovers: Daniel and Ti Moune.
* WomanScorned: Andrea verges on this, [[spoiler: though she is the one Daniel will marry. Averted, of course, with poor Ti Moune.]]
