"The Little Mermaid", sometimes translated in English as "The Little Sea Maid", is a fairy tale written by Danish author Hans Christian Andersen. Originally published in 1837 as part of a collection of fairy tales for children, the story follows the journey of a young mermaid princess who is willing to give up her life in the sea as a mermaid to gain a human soul.

A fairy tale is a short story that belongs to the folklore genre. Such stories typically feature magic, enchantments, and mythical or fanciful beings. In most cultures, there is no clear line separating myth from folk or fairy tale; all these together form the literature of preliterate societies. Fairy tales may be distinguished from other folk narratives such as legends and explicit moral tales, including beast fables. Prevalent elements include dragons, dwarfs, elves, fairies, giants, gnomes, goblins, griffins, merfolk, monsters, talking animals, trolls, unicorns, witches, wizards, magic, and enchantments.
